(?-Ethane-1,2-diamine-?N:N')bis-[bis-(ethane-1,2-diamine-?N,N')zinc(II)] tetra-kis-(perchlorate).

ABSTRACT: In the title salt, [Zn(2)(C(2)H(8)N(2))(5)](ClO(4))(4), an ethyl-enediamine mol-ecule bridges two bis-(ethyl-enediamine)-zinc units; the five-coordinate Zn atoms show a trigonal-bipyramidal coordination geometry that is distorted towards square-pyramidal (that of one Zn atom is distorted by 12% and that of the other by 34%). The perchlorate ions are all disordered over two positions in a 1:1 ratio. The cation inter-acts weakly with the anion by N-H?O hydrogen bonds, generating a three-dimensional network.
