New complexes of manganese(II) corresponding to [{(ArO)2PS2}2Mn] and [{(ArO)2PS2}2Mn.nL] (Ar = o-, m-, p-CH3C6H4 and p-Cl-m-CH3C6H3; n = 1, L = N2C12H8, N2C10H8; n = 2, L = NC5H5, P(C6H5)3) have been synthesized and characterized by microelemental analyses (C, H, and N), magnetic susceptibility, molar conductance, thermogravimetric, cyclic voltammetry, and spectral analyses including ESI mass spectrometry, IR, and UV-visible. The presence of a four-and-six coordinated Mn atoms has been established in the complexes and adducts, respectively. Antimicrobial screening of the complexes against gram negative bacteria E. coli, K. pneumonia, and P. aeruginosa and fungus S. rolfsii has shown potential bioactivity.
新的锰(II)配合物为 [{(ArO)2PS2}2Mn] 和 [{(ArO)2PS2}2Mn.nL](Ar = o-、m-、p-CH3C6H4 和 p-Cl-m-CH3C6H3;n = 1,L = N2C12H8,N2C10H8;n = 2,L = NC5H5,P(C6H5)3),通过元素分析(C、H 和 N)、磁化率、摩尔电导率、热重分析、循环伏安法和包括 ESI 质谱、IR 和 UV-可见光谱在内的光谱分析进行了表征。已在配合物和加合物中分别确定了四配位和六配位 Mn 原子的存在。对革兰氏阴性菌大肠杆菌、肺炎克雷伯菌和铜绿假单胞菌以及真菌 S. rolfsii 的复合物的抗菌筛选显示出潜在的生物活性。
