(H2NC2H4NH2)2Ni [(C3H3N2) Co (NH3)5]2 (CIO4)6 · 5H2O,NiCo2Cl6O29N18C10H62, Mr = 1288. 00, monoclinic, C2/c, a = 31. 832(4), b = 9. 691 (1), c=15. 425(4)(?),β=90. 71(2)°, Z = 4, V = 4758. 0(?)3, Dc=1. 798g/cm3, μ (MoKa) = 15. 22cm-1, F(000)=2656. The three metal nuclei, one Ni( Ⅱ ) and two Co( Ⅲ ), bridged by two imidazolyl anions (Im = C3H3N2), form an isosceles triangle. The Ni( Ⅱ ) atom is situated on the two-fold axis and coordinated by six nitrogen atoms to form a distorted octahedron with two nitrogen atoms from two Im in cis-positions. The two Co( Ⅲ ) atoms are related by C2 symmetry and each Co( Ⅲ ) is coordinated by six nitrogen atoms to form an octahedral configuration.
