A metalloligand type of synthetic route has been followed to generate a novel heterometallic three-dimensional (3D)-coordination polymer containing Cu­(II) and trimethyltin as nodes. The first step of this synthetic path consisted of the preparation of a two-dimensional-coordination polymer of Cu­(II), [Cu­(μ-LH)2]n (1) (LH2 = pyridine-2,5-dicarboxylic acid). The reaction of in situ generated 1 with Me3SnCl afforded the heterometallic 3D-coordination polymer, [Cu­(Me3Sn)2(μ-L)2]n (2). The latter is a 4,4-connected polymer with a sqc topology. This 3D-framework contains a paddle-wheel-shaped core comprised of two heterometallic (CuII/SnIV) macrocycles.
