摘要

The crystal structures of the title complexes (both triclinic, space group P1, Z = 1 for M = Mg, Z = 2 for M = Be) have been determined by low-temperature X-ray diffraction. They consist of non-coordinating ortho-benzenedisulfonimide anions and, respectively, inversion-symmetric octahedral [Mg(H2O)(6)](2+) cations or tetrahedral [Be(H2O)(4)](2+) cations and two non-coordinating water molecules. In both structures, all O-H hydrogen bond donor groups are used to associate the components into two-dimensional assemblies comprising an internal polar lamella of metal cations, (SO2)(2)N groups and water molecules, and hydrophobic peripheral regions consisting of vertically protruding benzo rings. Carbocycles drawn alternatingly from adjacent layers form pi-stacking arrays, whereby the aromatic rings display intercentroid distances in the range 340-370 pm. Several short C-H...O contacts, which may be viewed as weak hydrogen bonds, occur within and between the layers. [References: 24]

O接触,这些接触可能被视为弱氢键。 [参考:24]
