Poly[[bis{μ3-tris[2-(1H-tetrazol-1-yl)ethyl]amine}copper(II)] bis(perchlorate)]

Abstract

In the title compound, {[Cu(C9H15N13)2](ClO4)2}n, the Cu2+ cation lies on an inversion center and is coordinated by the tetrazole N4 atoms of six symmetry-equivalent tris[2-(1H-tetrazol-1-yl)ethyl]amine ligands (t3z) in the form of a Jahn–Teller-distorted octahedron with Cu—N bond distances of 2.0210 (8), 2.0259 (8) and 2.4098 (8) Å. The tertiary amine N atom is stereochemically inactive. The cationic part of the structure, viz. [Cu(t3z)2]2+, forms an infinite two-dimensional network parallel to (100), in pockets of which the perchlorate anions reside. The individual networks are partially interlocked and held together by C—H...O interactions to the perchlorate anions and C—H...N interactions to tetrazole N atoms.
