The crystal structure of the rigid bidentate nitrogen ligand bis[N-(2,6-diisopropylphenyl)imino]acenaphtene (abbr. o,o′i Pr2C6H3-BIAN) and three mixed- ligand copper complexes, namely [CuII(AcOH)(o,o′-iPr2C6 H3-BIAN)Cl2] (1), [CuII(acac)(AcOH)(o,o′-i Pr2C6H3-BIAN)]·(ClO4) (2) (where AcOH = acetic acid and acac = acetylacetonate) and [CuIBr(o,o′-i Pr2-p-BrC6H2-BIAN)]2 (3) are reported. In complexes 1 and 2, the coordination around the copper(II) centre is distorted square pyramidal with acetic acid molecule in the apical position. Two imine nitrogen atoms of o,o?-i Pr2C6H3-BIAN are occupying the basal plane together with two chloride atoms in case of 1 and two oxygen atoms (from acac ligand) in case of 2. In complex 3 the copper(I) ion is tetrahedrally surrounded by two imine nitrogen atoms of o,o′-i Pr2-p-BrC6H2-BIAN, and by two bridging bromide atoms. Complex formation is followed by certain structural changes inside the rigid N-N ligand. Such changes led to an increased planarity of the o,o′i Pr2C6H3-BIAN backbone, and produced a nearly perpendicular angle between the naphthalene and the aromatic imine planes.
