%X The title compound &#91;Zn2(2,3,2-tet)2(Im)&#93; (ClO4)3 (C17H43Cl3N10O12Zn2, 2,3,2-tet = N,N&#8242;-bis(2- aminoethyl)propane-1,3-diamine, Im = imidazolate anion) consists of an imidazolate-N,N&#8242;-bridged binuclear cation and three perchlorate anions. The complex crystallizes in the monoclinic space group C 2 with a 12 . 038(8), b 12 . 245(8), c 11 . 902(3) &#197;, &#946; 108 . 00(5)&#176;, V 1668 . 6(15) &#197;3 . The coordination geometry at each zinc(II) centre is approximately square-pyramidal. The Zn . . . Zn separation is 6 . 114(9) &#197;. Cyclic voltammetry shows two irreversible cathodic waves at &#8722; 1 . 00 and &#8722; 1 . 08 V/s.c.e., which clearly indicates that coordination of the strong-field ligands provides significant stability to the zinc(II) centre in the title complex.
