position are coordinated to Ni(II). Theoretical investigations using density functional theory calculations on the complexes were also performed which supports the distorted octahedral geometry around the nickel for the complexes. Hirshfeld surface analysis and 2D fingerprint plot analysis have been employed that display each significant interaction involved. In the complexes (3–5), H···H interactions are
由 N 供体配体稳定的八面体配位镍 (II) 配合物对应于 [(ArO)2PS2}2Ni·L2] [Ar = 4-(C2H5)C6H4 (3) 和 4-C(CH3)3C6H4 (4) ), (5); L = C5H5N (3), (4) 和 4-(C2H5)C5H4N (5)],已通过物理化学和光谱方法合成和表征。单晶 X 射线分析表明,NiS4 核位于赤道平面,两个相互转位的供体配体与 Ni(II) 配位。还对配合物进行了使用密度泛函理论计算的理论研究,这支持配合物镍周围扭曲的八面体几何形状。Hirshfeld 表面分析和 2D 指纹图分析已被采用,以显示所涉及的每个重要相互作用。在复合体(3-5)中,
