Synthesis and Crystal Structure of Trans-Bis(Acesulfamato Tetraaquazinc(II)

Abstract

The title compound, trans-bis(acesulfamato-O)tetraaquazinc(II) (I, C <inf>8</inf>H<inf>16</inf>N<inf>2</inf>O<inf>12</inf>S<inf>2</inf>Zn), crystallizes in the triclinic system, space group P1̄ with a = 5.1638(5), b = 8.5338(9), c = 9.9583(9) Å, α = 74.325(8), β = 81.112(7), γ = 75.800(8)°, V = 407.77(7) Å3, Z = 1, F(000) = 236, R<inf>int</inf> = 0.085, T = 296 K, the final R = 0.029 and wR = 0.078 for 1832 observed reflections with I > 2σ(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 R2<inf>2</inf>(8) and R2 <inf>2</inf>(16) rings, which lead to two-dimensional polymeric chains.
