Organotin(IV) selenate derivatives – Crystal structure of [{(Ph3Sn)2SeO4} ⋅ CH3OH] n

Abstract Crystallization of [(Ph 3 Sn) 2 SeO 4 ] ⋅ 1.5H 2 O in methanol leads to the formation of [{(Ph 3 Sn) 2 SeO 4 } ⋅ CH 3 OH] n ( 1 ) which constitutes a new specimen of organotin(IV) selenate derivatives. In the solid state, complex 1 is arranged in polymeric zig-zag chains, composed of alternating Ph 3 Sn and SeO 4 groups. In addition, pendant Ph 3 Sn ⋅ CH 3 OH moieties are branched along chains according to a syndiotactic organization and via Sn-O-Se connections. From a supramolecular point of view, intermolecular hydrogen bonds established between the selenate groups (uncoordinated oxygen) and the hydroxyl functions (CH 3 OH) of the pendant groups link the chains together.
