Crystal structure of tin(II) maleate monohydrate

Abstract

The structure of the title compound has been determined by the heavy-atom method from 822 diffractometer reflections and refined by full-matrix least-squares methods to R 0.030. Crystals are orthorhombic, space group P2₁ab, a= 7.35(1). b= 16.84(2), c= 5.32(1)Å, Z= 4. The tin atoms are in distorted square-pyramidal sites. Each maleate ion is bonded through three oxygen atoms to three different tin atoms (Sn–0 2.176, 2.196. 2.440 Å), and each tin atom is also bonded to a water molecule (Sn–O 2.312 Å).
