Poly[[bis­{μ(3)-tris­[2-(1H-tetra­zol-1-yl)eth­yl]amine}copper(II)] bis­(perchlorate)]

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 tetra­zole N(4) atoms of six symmetry-equivalent tris­[2-(1H-tetra­zol-1-yl)eth­yl]amine ligands (t (3) z) 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(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 inter­locked and held together by C—H⋯O inter­actions to the perchlorate anions and C—H⋯N inter­actions to tetra­zole N atoms.
