从头

The analysis results of crystal structure shows that the stoichiometric mononuclear Ni complex molecule C(subscript 37.5H45Cl2N10O12Ni was composed of two mononuclear Ni complex units {Ni[C35H33N10O](ClO4)2(CH3OH)2.5(H2O)0.5, Ni coordinated to the ligand to form hexacoordinated distorted octahedral configuration, and the orbital contribution and atomic net charge results has provided a good testimony for the coordinated condition in the crystal structure.

晶体结构分析表明，Ni单核配合物的化学经验式C37.5H45Cl2N10O12Ni的单胞中含有两个配合物分子{Ni[C35H33N10O](ClO4)2(CH3OH)2.5(H2O)0.5}，Ni与配位原子形成六配位的扭曲八面体结构。ab从头算所得原子轨道贡献和原子净电荷布居分析结果与晶体结构中的配位情况相符。
