Abstract

The new co-crystal copper(II) melamine complex poly[bis(mu-methacrylato)mu-(1,3,5-triazine-2,4,6-triamine)], C(19)H(26)Cu(2)N(6)O(8) (1) crystallizes in the triclinic P-1 space group with a = 8.9670(2) , b = 9.4108(2) , c = 15.4476(3) , alpha = 96.6090(10)A degrees, beta = 100.6270(9)A degrees, gamma = 95.5950(10)A degrees. Each Cu(II) exhibits a pseudooctahedral geometry. Four coplanar carboxylate oxygen atoms coordinated to the Cu(II) ion define the basal plane, whereas the apical position is occupied by one nitrogen atom from the melamine ligand. Here, the carboxylato-bridged two dinuclear copper(II) complexes are linked through melamine giving a 1D alternating chain. The structure of 1 consists of a two-dimensional supramolecular layer constructed by intermolecular N-H...N hydrogen bonds of the melamine ligands from adjacent one-dimensional [Cu(2)(C(4)H(5)O(2))(4)(C(3)H(6)N(6))] chains.
