Abstract

<jats:title>Abstract</jats:title> Tri-n-butyltin diphenylphosphinate (n-Bu)<jats:sub>3</jats:sub>SnO<jats:sub>2</jats:sub>PPh<jats:sub>2</jats:sub> has been synthesized by the reaction of (n-Bu<jats:sub>3</jats:sub>Sn)<jats:sub>2</jats:sub>O with Ph<jats:sub>2</jats:sub>POCl in toluene. An X-ray diffraction study of (n-Bu<jats:sub>3</jats:sub>)SnO<jats:sub>2</jats:sub>PPh<jats:sub>2</jats:sub> shows that the structure is polymeric and consists of helical chains in which (n-Bu)<jats:sub>3</jats:sub>Sn groups are linked by O-P-O bridges. The geometry about tin is trigonal bipyramidal, with n-butyl groups in equatorial positions and an axial O-Sn-O angle of 176.2 (2)°. IR and Raman spectra of (n-Bu)<jats:sub>3</jats:sub>SnO<jats:sub>2</jats:sub>PPh<jats:sub>2</jats:sub> are given and assigned. The mass spectrum is reported and discussed.
