Synthesis and structure of a new 1D infinite neutral chain based on organotin and selenious acid monoethyl ester

A new 1D infinite neutral chain (Ph3SnO2SeOCH2CH3)n (1) based on organotin and selenious acid monoethyl ester has been synthesized successfully and characterized by IR, elemental analysis, and X-ray single-crystal diffraction. In the compound 1, the Sn atom exists in slightly distorted trigonal bipyramidal geometry and the Se center is tri-coordinated with a distorted pyramidal arrangement. It is noted that the synthesis is facile and selenium oxide is directly introduced into synthesis route replacing organoseleninic acid under room temperature.
