The supramolecular interplay of the Ph 3 Sn+ unit and the [Cu(CN) 4 ]3− ion with either 4,4′-bipyridine (bpy), trans-1,2-bis(4-pyridyl)ethene (tbpe), 1,2-bis(4-pyridyl)ethane (bpe), pyrazine (pyz), or methylpyrazine (mepyz) as bidentate ligands in presence of H 2 O has been investigated for the first time. The products obtained have the general formula [(Ph 3 Sn) 3 Cu(CN)4·L·XH2O], where L is a bidentate ligand and X = 0–2. H 2 O molecules are usually coordinated to tin atoms and are involved in two significant O─H─N hydrogen bonds, wherein the nitrogen atoms belong either to the bidentate ligand or the M-coordinated cyanide ligands. The structures of these supramolecular coordination polymers were investigated by elemental analysis, X-ray powder diffraction, and IR, mass, and NMR spectra.
