title: Poly[[bis-{μ(3)-tris-[2-(1H-tetra-zol-1-yl)eth-yl]amine}copper(II)] bis-(perchlorate)].
abstract: In the title compound, {[Cu(C(9)H(15)N(13))(2)](ClO(4))(2)}(n), the Cu(2+) cation lies on an inversion center and is coordinated by the tetra-zole N(4) atoms of six symmetry-equivalent tris-[2-(1H-tetra-zol-1-yl)eth-yl]amine ligands (t(3)z) in the form of a Jahn-Teller-distorted octa-hedron 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(t(3)z)(2)](2+), forms an infinite two-dimensional network parallel to (100), in pockets of which the perchlorate anions reside. The individual networks are partially inter-locked and held together by C-H⋯O inter-actions to the perchlorate anions and C-H⋯N inter-actions to tetra-zole N atoms.
