monoclinic space group C2c. The complex cations 3 exhibit a binuclear structure with two terminal and one bridging halide ion, respectively. The compounds 1 and 2 are mononuclear species crystallizing in the orthorhombic space group P212121 in the case of 1 and in the triclinic space group in the case of 2·[MnBr4]. The ability of L1 and L2 to bind either two manganese ions naked or only one of them
第一种多核锰胍配合物和第一种含有单质子化双胍配体的锰配合物的合成和结构 含有中心吡啶官能团的两种不同烷基化双胍配体的金属化,即 N2,N6-双 (1,3-二甲基咪唑啉-2-亚基)pyridine-2,6-diamine (DMEG2py N7C15H23}, L1) 和 N2,N6-bis(1,1,3,3-四甲基-胍)pyridine-2,6-diamine (TMG2py N7C15H27}, L2),与溴化锰 (II) 和氯化锰形成新型络合物 [MnBr3(TMG2pyH)] ([MnBr3(N7C15H28)], (1)), [MnBr2(DMEG2pyH)2]2+ ([MnBr2(N7C15H24)2]2+, (2)) 和 [Mn2X3(DMEG2py)2]+ ([Mn2X3(N7C15H23)2]+; (3a): X = Cl; (3b): X = Br )。2 和 3 已被分离为四卤锰酸盐。单晶
