Bis[aqua(2,5-bis(4-pyridyl)-1,3,4-oxadiazole)thiocyanate] cadmium(II):: A three-dimensional framework built from hydrogen bonds and π-π stacking interactions

A three-dimensional (3D) network complex [Cd(L)(2)(NCS)(2)(H2O)(2)], L being 2,5-bis(4-pyridyl)-1,3,4-oxadiazole, has been synthesized and structurally determined by X-ray diffraction analysis: triclinic, space group P-1 with a = 7.8863(9) Angstrom, b = 8.6287(10) Angstrom, c = 11.4696(12) Angstrom, alpha = 94.346(2)degrees, beta = 109.331(2)degrees, gamma = 94.354(2)degrees, Mr = 713.04, V = 730.13(14) Angstrom(3), Z = 1. The crystal structure of the title complex reveals that it is a neutral molecule and the Cd(II) ion is at the center of symmetry. Each Cd(II) is six-coordinated and the CdN4O2 coordination sphere can be considered as an octahedron. The most striking feature of this complex resides in the formation of a 3D network through hydrogen bonds and pi-pi stacking interactions.
