    ABSTRACT: The title compound, C(34)H(52)N(2)O(2), is centrosymmetric, the mid-point of the central C-C bond being located on an inversion centre. Intra-molecular O-H⋯N and weak C-H⋯O hydrogen bonds are observed, but no significant inter-molecular inter-actions occur in the crystal structure.

    ABSTRACT: 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.

    ABSTRACT: In the title Schiff base compound, C23H30N2O2, the complete molecule is generated by crystallographic twofold symmetry, with one C atom lying on the rotation axis. The nonane chain adopts a linear conformation and the hydroxy group forms an intramolecular O—H...N hydrogen bond to the imine group.

    ABSTRACT: In the title Schiff base compound, C(23)H(30)N(2)O(2), the complete mol-ecule is generated by crystallographic twofold symmetry, with one C atom lying on the rotation axis. The nonane chain adopts a linear conformation and the hydr-oxy group forms an intra-molecular O-H⋯N hydrogen bond to the imine group.
