diphenyldithiophosphate complexes of Cr(III), [(ArO)2PS2}3Cr] [Ar = 2,4-(CH3)2C6H3 (1), 2,5-(CH3)2C6H3 (2),3,4-(CH3)2C6H3 (3), and 3,5-(CH3)2C6H3 (4)], have been synthesized and structurally characterized by IR, heteronuclear NMR (1H, 13C, and 31P) spectroscopic and single crystal X-ray analyses. The crystal structure of complex 4 reveals mononuclear units with the Cr(III) centre chelated in bidentate
图形摘要 摘要 Cr(III), [(ArO)2PS2}3Cr] [Ar = 2,4-(CH3)2C6H3 (1), 2,5-(CH3)2C6H3 (2),3, 的二甲基二苯基二硫代磷酸盐配合物, 4-(CH3)2C6H3 (3) 和 3,5-(CH3)2C6H3 (4)] 已合成并通过 IR、异核 NMR(1H、13C 和 31P)光谱和单晶 X 射线进行结构表征分析。配合物 4 的晶体结构显示了单核单元,Cr(III) 中心以双齿方式被三个二苯基二硫代磷酸酯配体的六个 S 原子螯合,形成八面体几何结构。该系统的主要核心由四元 (CrS2P)3 杂原子环和 Cr(III) 中心组成。评估了配体和复合物对六种细菌菌株(肺炎克雷伯菌、大肠杆菌、铜绿假单胞菌、枯草芽孢杆菌、金黄色葡萄球菌和鼠伤寒沙门氏菌)的抗菌潜力。
