The polymeric mononuclear Cu(II) complex, represented as [Cu(C2N3)2(NH3)2] n, features an asymmetric unit containing half a molecule completed by inversion symmetry, with the Cu(II) atom at its center.
The Cu(II) ion coordinates in a Jahn-Teller-distorted octahedral arrangement, where the arrangement involves two dicyanamide and two ammine ligands forming an approximate square plane.
The structure extends into a two-dimensional polymeric network due to the bidentate nature of the dicyanamide ligands and is further stabilized by hydrogen bonding interactions between ammine hydrogen atoms and neighboring dicyanamide ligands, creating a three-dimensional network
