title: Tetra-μ-methacrylato-κO:O'-bis-[(pyri-din-2-amine-κN)copper(II)].
abstract: In the title carboxyl-ate-bridged binuclear copper complex, [Cu(2)(C(4)H(5)O(2))(4)(C(5)H(6)N(2))(2)], each Cu(II) ion has a distorted square-based pyramidal environment formed by one N and four O atoms. The asymmetric unit contains two halves of two centrosymmetric mol-ecules, with Cu⋯Cu separations of 2.6498 (8) and 2.6528 (8) Å.
