A series of new 3d-metal complexes based on 2-amino-3-(1-methylbenzimidazol-2-yl)-4(5H)-ketothiophen (HL1) and 2-amino-3-(2-benzothiazolyl)-4(5H)-ketothiophen (HL2) were synthesized. Compounds of the general formulas [ML2] and [M(HL1)2Cl2] (where M = Co2+, Ni2+, Zn2+, Cu2+) were prepared by the reaction of the above mentioned ligands with the corresponding acetate (for [ML2]) or chloride (for [M(HL1)2Cl2])
摘要基于2-氨基-3-(1-甲基苯并咪唑-2-基)-4(5H)-酮噻吩(HL1)和2-氨基-3-(2-苯并噻唑基)-4的一系列新型3d金属配合物合成了(5H)-酮噻吩(HL2)。通式[ML2]和[M(HL1)2Cl2]的化合物(其中M = Co2 +,Ni2 +,Zn2 +,Cu2 +)是通过上述配体与相应的乙酸盐(对于[ML2]而言)或氯化物反应制得的(对于[M(HL1)2Cl2]的盐)在甲醇或甲醇-氯仿介质中的盐。初始金属盐中阴离子的选择以及配体的选择对于获得具有中性或去质子化形式的2-氨基-4(5H)-酮噻吩的配位化合物至关重要。因此,与HL1相反,在相同条件下无法获得具有HL2中性形式的配合物。所有的配合物均通过光谱法和X射线晶体学研究([CuL12]·H2O)。铜原子的配位多面体由来自两个配体阴离子的四个氮原子形成,配位球的几何形状介于四面体和方平面之间。
