Crystal structure and Hirshfeld surface analysis of bis­(3-aminopyrazole-κN (1))bis­(3-aminopyrazole-κN (2))bis­(nitrato-κO)copper(II)

In the crystal structure of the title compound, [Cu(NO(3))(2)(C(3)H(5)N(3))(4)], the Cu(II) atom is situated on an inversion center (Wyckoff position 2c of space group P2(1)/n) and shows an octa­hedral [N(4)O(2)] coordination environment. The axial positions are occupied by O atoms of nitrate anions, while the equatorial positions are taken up by the N atoms of four 3-amino­pyrazole ligands. As a result of the tautomerism of the latter, two coordinate with the N(1)-atom of 3-amino­pyrazole while the other two with the N(2)-atom. The presence of pyrrole-like N—H groups and amine substituents as donor groups leads to numerous intra- and inter­molecular hydrogen-bonding inter­actions, which were qu­anti­fied by Hirshfeld surface analysis.
