Bis(tetra-ethyl-ammonium) bis-(dimethyl-formamide)-tetra-kis-(μ-N,2-dioxido-benzene-1-carboximidato)penta-copper(II).

ABSTRACT: The title compound, (C(8)H(20)N)(2)[Cu(5)(C(7)H(4)NO(3))(4)(C(3)H(7)NO)(2)], abbreviated as (TEA)(2)[Cu(II)(12-MC(Cu(II) ) (N(shi))-4](DMF)(2) [where TEA is tetra-ethyl-ammonium, shi(3-) is salicyl-hydroximate (or N,2-dioxidobenzene-1-carboximidate) and DMF is N,N-dimethyl-formamide], contains five Cu(II) ions. Four of the Cu(II) ions are members of a metallacrown ring (MC), while the fifth Cu(II) is bound in a central cavity. Two of the ring Cu(II) ions are five-coordinate with distorted square-pyramidal geometry. The coordination sphere is composed of two shi(3-) ligands and one DMF mol-ecule. The other two ring Cu(II) ions and the central Cu(II) ion are four-coordinate with square-planar geometry. The coordination spheres of these ions are only composed of shi(3-) ligands. The charge of
