Two twisted 1,2-bis(2-pyridyl)ethyne ligands bridge two Cd2+ centers in the C2-symmetric title complex, [Cd2(NO3)4(-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)°. Owater-HOnitrate hydrogen bonding creates two-dimensional layers parallel to the ab plane.
