Poly[[bis(μ-4,4′-bipyridine-κ2N:N′)copper(I)] perchlorate 0.24-hydrate]

The title copper(I) polymeric compound, {[Cu(C10H8N2)2]ClO4·0.24H2O}n, obtained by the reaction of Cu(ClO4)2 and 4,4′-bipyridine (4,4′-bpy) under hydrothermal conditions, features a fourfold-interpenetrated diamondoid coordination framework. The asymmetric unit consists of two CuI atoms, three 4,4′-bpy ligands in general positions and two halves of two centrosymmetric 4,4′-bpy ligands, two ClO4 anions and water molecule with a site-occupancy factor of 0.480 (17). The CuI atoms are in a distorted tetrahedral coordination environment and are bridged by 4,4′-bpy ligands, forming a diamondoid cationic polymeric framework that encloses two symmetry-independent channels along [100], which accommodate perchlorate anions and water molecules.
