Coordination Modes of a Schiff Base Pentadentate Derivative of 4-Aminoantipyrine with Cobalt(II), Nickel(II) and Copper(II) Metal Ions: Synthesis, Spectroscopic and Antimicrobial Studies
measurements and spectral techniques like IR, UV and EPR. The nickel(II) complexes were found to have octahedral geometry, whereas cobalt(II) and copper(II) complexes were of tetragonal geometry. The covalency factor (beta) and orbital reduction factor (k) suggest the covalent nature of the complexes. The ligand and its complexes have been screened for their antifungal and antibacterial activities against
Co(II)、Ni(II) 和 Cu(II) 金属离子的过渡金属配合物,具有一般化学计量 [M(L)X]X 和 [M(L)SO(4)],其中 M = Co(II) , Ni(II) 和 Cu(II),L = 3,3'-硫代二丙酸双(4-氨基-5-乙基亚氨基-2,3-二甲基-1-苯基-3-吡唑啉)和 X = NO(3 )(-)、Cl(-) 和 OAc(-) 已通过元素分析、摩尔电导测量、磁化率测量和光谱技术(如 IR、UV 和 EPR)合成和结构表征。发现镍 (II) 配合物具有八面体几何形状,而钴 (II) 和铜 (II) 配合物具有四方几何形状。共价因子 (beta) 和轨道缩减因子 (k) 表明复合物的共价性质。已经筛选了配体及其复合物对三种真菌的抗真菌和抗菌活性,即
