摘要:
Two twisted 1,2-bis(2-pyridyl) ethyne ligands bridge two Cd2+ centers in the C-2-symmetric title complex, [Cd-2(NO3)(4)(mu-C12H8N2)(2)(H2O)(2)]. The bridging ligands arch across one another creating a 'zigzag loop' molecular geometry. Two nitrate ions and a water molecule complete the irregular seven-coordinate Cd-atom environment. The dihedral angles between the equivalent pyridyl ring planes of the two independent ligands are 67.2 (1)degrees. O-water-H...O-nitrate hydrogen bonding creates two-dimensional layers parallel to the ab plane.
