The magnetic properties of two series of dinuclear complexes, and one trinuclear complex, have been examined as a function of the bridging pathway between the metal centers. The first series of dinuclear complexes is [Mo(V)(O)(Tp)Cl}(2)(&mgr;-OO)], where "OO" is [1,4-O(C(6)H(4))(n)O](2)(-) (n = 1, 1; n = 2, 3), [4,4'-O(C(6)H(3)-2-Me)(2)O](2)(-) (4), or [1,3-OC(6)H(4)O](2)(-) (2) [Tp = tris(3,5-di
已经检查了两个系列的双核配合物和一个三核配合物的磁性,它们是金属中心之间的桥接路径的函数。第一系列双核配合物是[Mo(V)(O)(Tp)Cl}(2)(&mgr; -OO)],其中“ OO”是[1,4-O(C(6)H( 4))(n)O](2)(-)(n = 1,1; n = 2,3),[4,4'-O(C(6)H(3)-2-Me)( 2)O](2)(-)(4)或[1,3-OC(6)H(4)O](2)(-)(2)[Tp = tris(3,5-二甲基吡唑基)氢硼酸盐]。第二系列的双核配合物是[Mo(I)(NO)(Tp)Cl}(2)(&mgr; -NN)],其中“ NN”是4,4'-联吡啶(5),3,3 '-二甲基-4,4'-联吡啶(6),3,8-菲咯啉(7)或2,7-二氮杂py(8)。三核络合物是[Mo(V)(O)(Tp)Cl}(3)(1,3,5-C(6)H(3)O(3))](9),其晶体结构为测定[9
