Özet

The title compound, trans-bis(acesulfamato-O)tetraaquazinc(II) (I, C8H16N2O12S2Zn), crystallizes in the triclinic system, space group P (1) over bar with a = 5.1638(5), b = 8.5338(9), c = 9.9583(9) angstrom, alpha = 74.325(8), beta = 81.112(7), gamma = 75.800(8)degrees, V = 407.77(7) angstrom(3), Z = 1, F(000) = 236, R-int = 0.085, T = 296 K, the final R = 0.029 and wR = 0.078 for 1832 observed reflections with I > 2 sigma(I). The Zn-II centre resides on a centre of symmetry and has a distorted octahedral geometry. The basal plane is defined by two carbonyl 0 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 center dot center dot center dot O hydrogen bonds produce R-2(2)(8) and R-2(2)(16) rings, which lead to two-dimensional polymeric chains.
