摘要：

This work comprised the preparation of six complexes of Ni(II) and their study by spectroscopy and X-ray diffraction. These complexes are: [Ni(dppe)Cl-2]CH2Cl2 (1), [Ni(dppen)Cl-2] (II) [Ni(dppm)Br-2]CH2Cl2 (III), [Ni(dppe)(NCS)(2)] (IV), [Ni(dppen)I-2] (V), [Ni(dppp)Cl-2]CH2Cl2 (VI), where dppe=1,2-bis(diphenylphosphine)ethane, dppen=cis-1,2-bis(diphenylphosphine)ethene, dppm=bis(diphenylphosphine)methane, dppp=1,3-bis(diphenylphosphine)propane. The structures of complexes III-VI are unknown in the literature. Although the molecular structures of the six complexes present many similarities, their crystalline arrangements vary considerably. This is a feature not presented hitherto in previous work involving complexes of this type. In addition, a systematic spectroscopic study was undertaken on all six complexes.
