The title compound [Ag(CH3CONHC(S)NH2)2](NO3) has been prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction. It crystallizes in mo-noclinic, space group P21/c with Mr = 406.20 (C6H12Ag N5O5S2), a = 12.0680(6), b = 6.8056(5), c = 18.0173(1) ? b = 111.383(4), V = 1377.9(2) 3, Z = 4, Dc = 1.958 g/cm3 , F(000) = 808, = 1.789 mm-1, R = 0.0361 and wR = 0.1015. Of 4185 reflections ((2)max = 55.00?, 3147 were unique (Rint = 0.0174) and 2820 with I > 2(I) were used to solve the structure. The silver(I) atom adopts V-shape geometry with the AgS bond distance of 2.4271(7) and 2.7229(9) , respectively. Seven atoms of one acetylthiocarbamide ligand are coplanar, while only four atoms of another acetylthio-carbamide ligand are fairly planar. The [Ag(CH3CONHC(S)NH2)2]+ cation and nitrate anion NO3- are connected by hydrogen bonds to form a three dimensional hydrogen bonding network..

The title compound [ClCH2(C7H6N2)]NO3 has been prepared and characterized by elemental analysis and X-ray studies. It crystallizes in the monoclinic system, space group P21/n with a = 7.4189(3), b =15.3064(6), c = 9.2657(3) ? b = 102.449(2)? C8H8ClN3O3, Mr = 229.62, V = 1027.44(7) 3, Z = 4, Dc = 1.484 g/cm3, F(000) = 472, = 0.363 mm-1, R = 0.0671 and wR = 0.1546. The crystal structure consists of discrete 2-chloromethyl-1H-benzimidazole cations and NO3- anions. The benzimidazole ring with the conjunction carbon atom C(1) is fairly planar, with the deviation from the least plane through the ring atoms is smaller than 0.010(3) ? The analytical results of crystal structure show that three different non-covalent interactions in the compound, NH…O intermolecular hydrogen bonds, CH…O interaction and p-p stacking interaction, play an important role in the crystal packing.

A mixed-valence dinuclear manganese complex, [Mn ⅡMn ⅢL](ClO 4)·1/2MeOH, where L is a macrocyclic ligand derived from the cyclocondensation of sodium 2,6-diformyl-4-methylphenolate with N,N-bis(2-aminoethyl)-2-hydroxybenzyl amine, was obtained and its structure was determined by X-ray diffraction. The orange crystal is a monoclinic system with space group P2 1/c and lattice parameters a=1.1617(4), b=1.4005(3), c=1.4641(3) nm, β=113.03(2)°, and Z=2. The crystal structure shows that each pendant-arm is bonded in a bidentate fashion to the adjacent metal atom and that both the arms are on the same side of the macrocycle. The two Mn atoms are bridged by two μ 2-phenoxy oxygen atoms of the tetra-imine macrocycle, and each Mn atom, locating in a trigonal prismatic coordination environment(N 3O 3), is six-coordinated by the two imine nitrogen atoms, one tertiary nitrogen atom and a pendant phenol moiety apart from the two oxygen atoms.

A Trihydrated complex of benzimidazole copper(Ⅱ) sulfate [(C 7H 6N 2) 4CuSO 4]·3H 2O was synthesized and structurally characterized. The crystal structure of this compound is built up of six solvated water molecules and two dissimilar copper ions identified as Cu1 and Cu2. The coordination geometry of copper(Ⅱ) is a slightly distorted square pyramid. The four equivalent tertiary nitrogen atoms of the benzimidazole ligand form an equatorial plane, while the oxygen atoms of sulfato occupy the axial site. In the solid state, the title compound forms a three dimensional network structure via hydrogen bonds. The benzimidazole, sulfato ion and H 2O moieties are connected by the intermolecular hydrogen bonds. The (EPR) spectrum shows axial symmetry with g ⊥=2.039 and g ‖=2.285. Variable temperature magnetic susceptibility shows that there is a weak antiferromagnetic interaction between the neighboring copper(Ⅱ) ions.

The crystal structure of [CoCl(C_7H_5N_2CH_2COPh)_4]Br has been determined by means of X-ray crystallography. The molecular structure consists of a discrete [CoCl(C_7H_5N_2CH_2COPh)_4]+ cation and one Br- anion. In the [CoCl(C_7H_5N_2CH_2COPh)_4]+ cation, the coordination geometry of the central Co atom is square-pyramidal with four tertiary N atoms of benzimidazole from four α-(benzimidazol-1-yl)-hypnone ligands in the basal position and one chloride anion in the apical position. In the solid state, [CoCl(C_7H_5N_2CH_2COPh)_4]+ and Br- anion possess intermolecular and intramolecular interactions, which stabilize the crystal structure. The characterization of the title compound were also carried out by using elemeutal analysis, FTIR, UV spectrometries and TG-DSC.

Five novel triazole compounds containing group 1,3-dioxolane were designed and synthesized by taking difenoconazole as the start compound and changing diphenyl ether for benzyl phenyl ether. Their structures were confirmed by elemental analyses, ()~1H NMR and IR spectra. The single crystal structure of 2-[4-(2,4-dichlorophenylmethoxy]phenyl-2-(1,2,4-triazol-1-yl)methane-1,3-dioxolane was determined by means of (X-ray) diffraction. The preliminary bioassays showed that the synthesized compounds exhibited some activities of fungicides and plant growth regulators.

The structure of chiral N-ethyl-N-(2,3,4,6-tetra-O-acetyl-b-D-glycosyl)-thio- carbamide was determined by X-ray diffraction method. It crystallizes in the monoclinic system, space group P21 with a = 7.6560(15), b = 10.311(2), c =14.181(3) ? b =100.88(3), C17H26N2O9S, Mr = 434.46, V = 1099.3(4) ?, Z = 2, Dc = 1.312 g/cm3, F(000) = 460, m = 0.196 mm-1, R = 0.0704 and wR = 0.1655. The total independent reflections were 5098, of which 1875 were observed with I ≥2s(I). The hexopyranosyl ring adopts a chair conformation. All the ring substituents are in the equatorial positions. The acetoxylmethyl group is in the gauche-gauche conformation. The S atom is in synperiplanar conformation, while the NCNC linkage is antiperiplanar. X-ray analysis shows that the absolute configuration of the chiral carbon atom at C(1) was proved to be b-form. The 1H NMR spectra and IR are in good agreement with the result of crystallography analysis. The NH…O intermolecular hydrogen bonds link the molecules into infinite chains connected by CH…O interactions.

针对丝网印刷碳纳米管(CNT)阴极,提出用电解液法进行表面后处理,有效改善碳纳米管阴极场发射特性。利用扫描电子显微镜表征电解液法处理前后CNT阴极表面形貌变化,并对处理前后CNT阴极进行场发射特性测试。结果表明,电解液法处理后有更多的CNT伸出有机浆料表面,开启电场从2.4V/μm降低到1.4V/μm,同样面积的薄膜(印制面积为1cm×1cm)在3.0V/μm场强下的发射电流由100μA提高到了1800μA,说明电解液处理对于提高薄膜的场发射特性有明显作用。该方法在碳纳米管场发射显示器的制作中具有很好的实际应用价值。
