Abstract
Crystals of the title compound are monoclinic, space group p21/c with a= 11.1956(12), b= 14.3477(12), c= 16.2180(15)Å, β= 123.36(1)°, and Z= 4. All atoms were located from a single-crystal X-ray analysis based on counter data. The structure was refined to a final R of 0.037 for 2 485 observed reflexions. The complex contains a planar terdentate NNN-donor-set [Cu–N(central) 1.913(3), mean Cu–N(term) 2.041 (6)Å], and both unidentate [Cu–O 2.213(4)Å] and asymmetric bidentate [Cu–O 1.968(3), 2.533 (5)Å] nitrato-groups. The copper atom co-ordination is distorted from regular octahedral by a mainfestation of the static Jahn–Teller effect and by the bite of the terdentate ligand.Keywords
