title: Bis(nitrato-κO)tetra-kis-[1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one]copper(II).
abstract: In the title complex, [Cu(NO(3))(2)(C(11)H(11)N(3)O)(4)], the Cu(II) atom is situated on a centre of inversion and is coordinated by two O atoms from two nitrate anions and four N atoms from four monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands in a distorted octa-hedral geometry. Weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds result in a supra-molecular layer parallel to (101). These layers are connected by π-π inter-actions between the benzene rings [centroid-centroid distance = 3.891 (2) Å].
