Crystal Structure of a New Heterotrinuclear Complex, [Cu(C2H8N2)2][{HB(C3H3N2)3}Fe(CN)3

Abstract

The title compound, [Cu(C2H8N2)2][{HB(C3H3N2)3}Fe(CN)3]2, crystallizes in the monoclinic space group P21/c with a = 34.924(2)A, b = 7.923(2)A, c = 13.546(2)A, β = 96.201(3)°, V = 3726.3(11)A3, Z = 4. The structure was refined to a final R value of 0.0622 for 4365 reflections (I > 2σ(I)). The copper atom is in a distorted octahedral environment: two cyano nitrogen atoms in trans positions and four nitrogen atoms from the ethylenediamine molecules. The intramolecular Fe(1)-Cu(1), Fe(2)-Cu(1) and Fe(1)-Fe(2) distances are 5.199, 5.211 and 10.410 A, respectively.
