title: Dichlorido[μ-10,21-dimethyl-2,7,13,18-tetra-phenyl-3,6,14,17-tetra-aza-tricyclo-[17.3.1.1]tetra-cosa-1(23),2,6,8,10,12(24),13,17,19,21-deca-ene-23,24-diolato]dicopper(II) ethanol hemisolvate dihydrate.
abstract: The dinuclear title complex, [Cu(2)(C(46)H(38)N(4)O(2))Cl(2)]·0.5C(2)H(5)OH·2H(2)O, is located on crystallographic inversion centres with two half-mol-ecules in the asymmetric unit. The two Cu(II) atoms are coordinated by a hexa-dentate dianionic ligand formed in situ from the condensation of two tridentate ligands by four imine N atoms and two bridging phenolate O atoms along with two Cl atoms at axial positions. The coordination geometry around the metal atoms is distorted square-pyramidal (τ = 0.185 and 0.199). The non-bonding Cu⋯Cu distances are 2.9556 (12) and 2.9506 (12) Å in the two dimers. The packing is stabilized through solvent-mediated inter-molecular O-H⋯O and O-H⋯Cl hydrogen bonds. The diamine chain of one of the dimers is disordered over two positions in a 0.680 (5):0.320 (5) ratio.
