【摘要】 <正> 标题化合物ZnL₂Cl₂（L:=N—（O）-N（CH₃）₂）,是在开拓水中痕量重金属属离子的新显色剂时发现的,晶体呈深红色,它的单晶也是顺磁研究很好的基质材料。作为C—亚硝基化合物系统研究之一,发现配体的晶体（绿色）虽具无序结构特征,业已呈现因二甲胺基的电子授予性质而产生的弱醌型分子结构类型。本研究不仅可查明标题化合物中心原子配位情况,对配体的分子结构也可有进一步的了解。更多还原

【Abstract】 The titled compound ZnL2Cl2(L:O = N-O-N(CH3)2) (crimson) vas prepared during the development of colorimetrie reagent for traces of heavy metals in,water by the reaction of ZnCl2 with prnitrosodimethylaniline (green).The crystals are orthorhombic,space group Pbca,a=14.262(6),b=28.850(8),c=9.155(3)A with Z=8.The data were collected on a modified Picker diffractometer using NRCC collector package with line profile analysis,structure solved and refined using XRAY 76 to a R value of 0.050 using 2232 independent reflections.The coordination about the Zn atom is a dightly distorted tetrahedron and the phenyl rings show an obvious quinonoid character.更多还原
