The reaction of CuI with cinchonine （an organic donor-acceptor chromophore） afforded a homochiral 3D diamondoid network [Cu4I4（cinchonine）2]n （1） containing a cubane cluster （Cu4I4） as a connecting node. This is the first homochiral coordination polymer with diamondoid nets containing a cluster as a connecting note. Its thermal stability and solid state optical properties such as fluorescence, circular dichroism and second-harmonic generation response were also reported.

To synthesize and study the relation between structure and characteristics of Co-Cbond of coenzym B12 model compounds, it is an effective way to understand the fac-tors which can influence the stabilities of Co-C bond and the mechanism of mutasecatalyzed substrate rearrangement. Unfortunately knowledge about micro reaction mecha-nism of the model compounds is limited. W. N. Lipscomb calculated the

The title compound (PhNHNH)2C=OCH3CN has been prepared and characterized by elemental analysis and IR spectrum studies. The single-crystal X-ray structure determination of the title compound was carried out. It crystallizes in the monoclinic system, space group P21/n with a = 5.7818(2), b = 15.320(1), c = 17.469(1) ? b = 97.476(1)? V = 1534.2(1) 3, Mr = 283.34 (C15H17N5O), Z = 4, Dc = 1.227 g/cm3 , F(000) = 600, ?= 0.082 mm-1, R = 0.0561 and wR = 0.1538. The total reflections were 8214 and the independent ones were 2624 (Rint = 0.0559), of which 1756 were observed with I > 2s(I). The torsion angles of the important groups (C(6)N(1) N(2)C(7) and C(7)N(3)N(4)C(8)) are 68.3(3) and 93.3(3), respectively. In the crystal lattice, the molecules form a network structure through hydrogen bonds. The crystal structure is stabilized by NH…N and NH…O hydrogen bonds. FT-IR spectra clearly show there exist acetonitrile molecules in the crystal lattice.

As one of the most commonly used features, Mel-frequency cepstral coefficients(MFCCs) are less discriminative at high frequency. A novel technique,known as Deep scattering spectrum(DSS), addresses this issue and looks to preserve greater details. DSS feature has shown promise both on classification and recognition tasks. In this paper, we extend the use of DSS feature for acoustic scene classification task. Results on Detection and classification of acoustic scenes and events(DCASE) 2016 and 2017 show that DSS provided 4.8% and 17.4% relative improvements in accuracy over MFCC features, within a state-of-the-art time delay neural network framework.

A novel viologen（4,4＇bipyridinium）-based complex （CH3-4,4＇-H2bipy）（HgCl4）（1）,in which the CH3-4,4＇-H2bipy （MQ2＋） was generated in situ,has been synthesized via hydrothermal reaction and structurally characterized. Complex 1 crystallizes in the space group P21/c of monoclinic system with four formula units in a cell：a = 8.1848（6）,b = 21.809（2）,c = 9.0285（6） ,β = 107.377（1）°,V = 1538.0（2） 3,C11H11Cl4HgN2,Mr = 513.61,Dc = 2.218 g/cm3,S = 1.009,μ（MoKα） = 10.685 mm-1,F（000） = 956,R = 0.0360 and wR = 0.0812. The crystal structure analysis reveals that the title complex features an isolated structure based on a CH3-4,4＇-H2bipy moiety and a mercury atom terminally bound by four chlorine atoms. Photoluminescence investigation reveals a strong emission in blue region,which may originate from π→π＊ charge-transfer interaction of the CH3-4,4＇-H2bipy moiety.
