Ni contacts are observed between anions and cations in the crystal structure.
O hydrogen bond involving the NH imine H atom and the phenolate O atom.
There is a centre of symmetry at the mid-point of the Pr. O hydrogen bonds link the molecules, forming a network, which may be effective in the stabilization of the crystal structure.
A crystallographic threefold rotoinversion axis passes through the Cr atom. The conformers are linked by bifurcated three-centre hydrogen bonds, forming chains running along the a axis. O intramolecular hydrogen bonds lead to the formation of a sequence of five-, six- and five-membered rings, respectively, which are edge-fused.
The pyridyltetrazolate anions serve to bridge the different copper ions into an almost flat ribbon.
