Synthesis and crystal structure of trans-bis(acesulfamato-O) tetraaquazinc(II)

Abstract

The title compound, trans-bis(acesulfamato-O)tetraaquazinc(II) (I, C 8H16N2O12S2Zn), crystallizes in the triclinic system, space group P1? with a = 5.1638(5), b = 8.5338(9), c = 9.9583(9) Å, ? = 74.325(8), ? = 81.112(7), ? = 75.800(8)°, V = 407.77(7) Å3, Z = 1, F(000) = 236, Rint = 0.085, T = 296 K, the final R = 0.029 and wR = 0.078 for 1832 observed reflections with I > 2?(I). The ZnII centre resides on a centre of symmetry and has a distorted octahedral geometry. The basal plane is defined by two carbonyl O atoms of two monodentate trans-oriented acesulfamato ligands and two trans-aqua ligands. The axial positions in the octahedron are occupied by two trans-aqua ligands. Intermolecular O-H?O hydrogen bonds produce R22(8) and R2 2(16) rings, which lead to two-dimensional polymeric chains.
