Stereochemistry of flexible-chelate–metal complexes. Part III. Crystal structure of dihydrogen ethylenediaminetetra-acetatostannate(II)

Abstract

The crystal structure of the title compound has been determined from three-dimensional diffractometer data. The orthorhombic unit cell, space group Pbca, has dimensions a= 659·1 (1), b= 1303·1 (2), c= 3221·6(6) pm, and Z= 8. The structure was solved by Patterson and Fourier methods, refined by least squares to R 0·056 for 2130 observed reflections. The tin atom is centred in the rectangular face of a distorted triangular prism (Sn–N 238·8 and 244·2, Sn–O 219·6, 234·3, 263·5, and 305·7 pm). Intermolecular hydrogen bonds link carboxy-groups from differing molecules forming a one-dimensional polymer in the b direction.
