Two new compounds, [Ni2（L1）（Py）6]Py·CH3OH（1） and [Ni3（LZ）2（PY）4]·2DMF（2）（H4L1=N,N＇-bisalicyl-bisthiocarbamide; H3L2=3-hydroxyl-2-naphthalene thiosemicarbazide; Py=pyridine; DMF=dimethyl fumarate）, based upon two thiosemicarbazone ligands have been obtained and characterized by elemental analysis, Fourier transform infrared（FTIR） and X-ray diffraetion（XRD）. Compound 1 possesses a binuclear cluster, in which the bisalicylbisthi- ocarbamide acts as a hexadentate bridge. Compound 2 exhibits a linear trinuclear cluster with the triply-deprotonated ligand acting as pentadentate bridge. C--H…O, C--H…π and C--…S weak interactions further link these molecules to form interesting supramolecular networks.

Polystyrene-supported hydroquinone （PS-HQ） is presented as an in situ polymeric cocatalyst to replace polystyrenesupported benzoquinone （PS-bq） in the PdCl2-catalyzed acetalization of methyl acrylate with methanol in supercritical carbon dioxide （scCO2） under oxygen atmosphere. Due to deletion of H2O2 oxidation step, PS-HQ is more convenient and relatively inexpensive.

以‘太行’白羊草(Bothriochloa ischaemum)为材料,通过盆栽试验探究了土壤微生物对干旱胁迫下白羊草幼苗植株生长及生理生化的影响。结果表明:与未灭菌土壤处理相比,干旱和非干旱条件下土壤灭菌处理显著降低了植株的株高、茎粗、地上部和地下部干鲜重及叶绿素含量,提高了超氧化物歧化酶(Superoxide dismutase,SOD)、过氧化物酶(Peroxidase,POD)、过氧化氢酶(Catalase,CAT)活性以及丙二醛(Malondialdehyde,MDA)、可溶性蛋白和可溶性糖含量。然而在持续干旱条件下,添加土壤菌悬液处理的白羊草幼苗植株的株高、地上部鲜干重和地下部干重、总叶绿素含量、可溶性糖和可溶性蛋白含量显著提高;SOD,POD活性和MDA含量显著降低。说明土壤微生物能够有效缓解干旱胁迫对白羊草幼苗生长的抑制作用,本研究对进一步认清土壤微生物对白羊草生长和抗旱作用的影响以及对微生物菌种资源的开发利用具有重要意义。
