ABSTRACT: The title complex, [Cu(2)(C(22)H(20)Br(2)N(4)O(2))(ClO(4))(2)], was prepared by the condensation of 2,6-diformyl-4-bromo-phenol with 1,3-diamino-propane in the presence of copper(II) ions. The macrocyclic ligand shows an approximately planar structure except for the two propene groups in the macrocycle. The coordination polyhedron of each Cu atom can be described as distorted square pyramidal. The two Cu atoms are bridged by two phenolate O atoms of the macrocycle, with a Cu?Cu distance of 3.109?(2)?Å.

Bis(μ-hexa-deca-noato-κO:O)bis-[(2,2'-bipyridine-κN,N')(hexa-deca-noato-κO)copper(II)] methanol disolvate.

Project description:The asymmetric unit of the title compound, [Cu(2)(C(16)H(31)O(2))(4)(C(10)H(8)N(2))(2)]·2CH(3)OH, contains one half-mol-ecule of the metal complex solvated by a methanol mol-ecule. In the complex, two of the metal atoms are doubly bridged by two monodentate bridging hexa-deca-noate ligands around a center of inversion. The square-pyramidal geometry around each Cu(II) ion is completed by a terminal hexa-deca-noate O atom and two N atoms from a 2,2'-bipyridine ligand. The alkyl chains of the carboxyl-ate ligands are arranged in a parallel manner with an all-trans conformation. In the crystal, a π-π inter-action formed by the bipyridine rings [centroid-centroid separation = 3.7723 (17) Å] and inter-molecular C-H⋯O hydrogen bonds link the complex mol-ecules into infinite chains along the b axis. An O-H⋯O interaction between the methanol solvate and one of the carboxylate O atoms is also observed.

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 (? = 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.
