Abstract Reaction of the triethylammonium salt of the substituted diphenyldithiophosphate ligands with AsCl3 in a 3:1 ratio results in the formation of the arsenic complexes As[S2P{OC6H4(4-C2H5)}2]3 (1), As[S2P{OC6H4(4-(CH3)3C)}2]3 (2), As[S2P{OC6H3(2,4-CH3)2}2]3 (3), As[S2P{OC6H3(2,5-CH3)2}2]3 (4), As[S2P{OC6H3(3,4-CH3)2}2]3 (5), and As[S2P{OC6H3(3,5-CH3)2}2]3 (6). The characterization of all the synthesized complexes was done by IR and multinuclear NMR (1H, 13C, and 31P) spectroscopies. Complexes 1 and 2 were structurally elucidated by single-crystal X-ray analysis. The X-ray data reveals that 1 and 2 were crystallized in triclinic crystal system with space group P−1 and monoclinic crystal system with space group C2/c, respectively. In 1 and 2, the coordination geometry around the central arsenic atom is pseudo-trigonally distorted octahedral with a lone pair of electrons positioned on one of the triangular faces of the octahedral. The central As atom in both complexes is surrounded by six sulfur atoms of the chelating anisobidentate ligands. The density functional theory computations are also carried out to further analyze the geometry and quantum chemical parameters in order to support the experimental and structural data. Finally, to estimate the effect of alkyl steric bulk in diphenyldithiophosphate complexes 1 and 2 on the intermolecular contacts contributions to the Hirshfeld surface analysis and 2-D finger-print plots analysis have been employed.

取代的二苯基二硫代磷酸砷 (III) 配合物:合成、表征、单晶 X 射线、DFT 和 Hirshfeld 表面分析

摘要 取代的二苯基二硫代磷酸酯配体的三乙基铵盐与 AsCl3 以 3:1 的比例反应形成砷配合物 As[S2P{OC6H4(4-C2H5)}2]3 (1), As[S2P{OC6H4 (4-(CH3)3C)}2]3 (2), As[S2P{OC6H3(2,4-CH3)2}2]3 (3), As[S2P{OC6H3(2,5-CH3)2 }2]3 (4), As[S2P{OC6H3(3,4-CH3)2}2]3 (5), and As[S2P{OC6H3(3,5-CH3)2}2]3 (6) . 所有合成配合物的表征均通过 IR 和多核 NMR(1H、13C 和 31P)光谱进行。通过单晶 X 射线分析在结构上阐明了配合物 1 和 2。X射线数据显示,1和2分别在空间群为P-1的三斜晶系​​和空间群为C2/c的单斜晶系中结晶。在 1 和 2 中,中心砷原子周围的配位几何是伪三角扭曲八面体,一对孤对电子位于八面体的三角形面上。两个配合物中的中心 As 原子被螯合双齿配体的六个硫原子包围。还进行了密度泛函理论计算以进一步分析几何和量子化学参数,以支持实验和结构数据。最后,为了估计二苯基二硫代磷酸酯配合物 1 和 2 中烷基空间体积对 Hirshfeld 表面分析和二维指纹图分析的分子间接触贡献的影响。图形概要 两个配合物中的中心 As 原子被螯合双齿配体的六个硫原子包围。还进行了密度泛函理论计算以进一步分析几何和量子化学参数,以支持实验和结构数据。最后,为了估计二苯基二硫代磷酸酯配合物 1 和 2 中烷基空间体积对 Hirshfeld 表面分析和二维指纹图分析的分子间接触贡献的影响。图形概要 两个配合物中的中心 As 原子被螯合双齿配体的六个硫原子包围。还进行了密度泛函理论计算以进一步分析几何和量子化学参数,以支持实验和结构数据。最后,为了估计二苯基二硫代磷酸酯配合物 1 和 2 中烷基空间体积对 Hirshfeld 表面分析和二维指纹图分析的分子间接触贡献的影响。图形概要 估计二苯基二硫代磷酸酯配合物 1 和 2 中烷基空间体积对 Hirshfeld 表面分析和二维指纹图分析的分子间接触贡献的影响。图形概要 估计二苯基二硫代磷酸酯配合物 1 和 2 中烷基空间体积对 Hirshfeld 表面分析和二维指纹图分析的分子间接触贡献的影响。图形概要
