cis-(Nitrato-κ2OO′)(25579121214-octa­methyl-14811-tetra­aza­cyclo­tetra­decane-κ4NN′N′′N′′′)cadmium nitrate hemihydrate

摘要

The Cd^II atom in the title complex, [Cd(NO3)(C18H40N4)]NO3·0.5H2O, is coordinated within a cis-N4O2 donor set provided by the tetra­dentate macrocyclic ligand and two O atoms of a nitrate anion; the coordination geometry is distorted octa­hedral. The lattice water mol­ecule is located on a twofold rotation axis. N—H⋯O hydrogen bonds and weak C—H⋯O inter­actions link the complex cations into a supra­molecular layer in the bc plane. Layers are connected by O—H⋯O hydrogen bonds between the lattice water mol­ecule and the non-coordinating nitrate anion, as well as by weak C—H⋯O contacts.
