摘要：

A novel compound catena-(mu-CrO4-O,O')[Ni(L-1)Ni(L-2)]. 3H(2)O (1) (L-1 = 3,5,10,12-tetramethyl-1,4,8,11-tetraazacyclotetradecane and L-2 = 2,5,9,12-tetramethyl-1,4,8,11-tetraazacyclotetradecane) has been synthesized for the first time and structurally characterized. 1 crystallizes in the triclinic space group P (1) over bar with a = 9.623(1), b = 10.084(1), c = 12.723(3) Angstrom, alpha = 66.74(2), beta = 75.20(1), gamma = 72.02(1)degrees, V = 1066.2(3) Angstrom(3), and Z = 2. The coordination environment around the Ni(II) ions is an axially elongated octahedron with the secondary amines of the isomeric ligands and two oxygen atoms of [CrO4](2-).
