Coordination compounds of organotin(IV) with diverse dimensionalities are obtained due to the ability of the tin atoms to have different coordination numbers, such as 4, 5, 6, or 7 [1].
New 1-D organotin(IV) polymers were obtained starting from triphenyltin chloride (Ph3SnCl) and, concurrently, two different bidentate organic ligands: one having N donor atoms, such as 1,2-bis(4-pyridyl)ethane (bpa) or 4,4′ azopyridine (azopy), and the other one having O donor atoms, such as for example terephthalate (tpa), 2-aminoterephtalate (atpa), or naphthalene dicarboxylate (ndc). Elemental analysis, spectroscopic techniques, such as FTIR and UV–Vis, as well as single crystal and powder X-ray diffraction were used to characterized the obtained compounds.
Five new polynuclear coordination compounds with the general formula {(Ph3Sn)(L1)(Ph3Sn)(L2)}n, where L1 = bpa and L2 = tpa (compound 1), L1 = bpa and L2 = atpa (compound 2), L1 = bpa and L2 = ndc (compound 3), L1 = azopy and L2 = tpa (compound 4) and L1 = azopy and L2 = ndc (compound 5, Figure 1) have been synthesized and characterized. The resulting complexes were 1-D coordination polymers in which the triphenyltin(IV) nodes were linked by alternating dicarboxylate and organic diamines ligands. The tin(IV) atoms exhibit a trigonal bipyramidal geometry, with the three phenyl groups in equatorial positions, while O and N atoms from the spacers are in apical positions.
The resulting compounds showed an interesting and quite rare feature in the chemistry of organotin coordination polymers, namely that the organotin(IV) nodes are connected through alternating ligands ofcarboxylato anions and organic diamines.
