Synthesis, spectroscopic study, and crystal structure of a new organotin (IV) selenate derivative

The polymeric organotin (IV) selenate complex [(Me 3 Sn) 3 (SeO 4)(OH)] n (1) has been isolated as single crystals from the reaction of [(Me 2 NH 2) 2 SeO 4] and Me 3 SnCl in methanol. In the solid state, compound 1 was characterized by X-ray diffraction analysis, Fourier transform-infrared spectroscopy, and elemental analysis. 1 crystallizes in the orthorhombic system space group Pbca with a= 11.0231 (2) Å, b= 16.3461 (3) Å, c= 20.9945 (4) Å, ?= ?= ?= 90, V= 3782.89 (12) Å 3, and Z= 8. Its structure can be described as a polymeric zigzag chain based on Me 3 Sn moieties linked by tridentate selenate anions. Pendant (Me 3 Sn) 2 OH groups are also connected to the chain, according to a syndiotactic organization, and via Sn-O-Se bonds. Intermolecular OH••• O hydrogen bonds and long Se-O••• Sn distance interactions promote the association of chains together and lead to the propagation of a three-dimensional
