{?(2)-1,4-Bis[2-(4-pyrid-yl)ethen-yl]benzene-?N:N'}bis-[bis-(acetyl-acetonato-?O,O')copper(II)].

ABSTRACT: The asymmetric unit of the title compound, [Cu(2)(C(5)H(7)O(2))(4)(C(20)H(16)N(2))], contains half of a centrosymmetric dinuclear mol-ecule. In the mol-ecule, each Cu center is coordinated by four O atoms from two acetyl-acetonate ligands and one N atom from the bridging linear 1,4-bis-[2-(4-pyrid-yl)ethen-yl]benzene ligand in a square-pyramidal geometry. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into sheets parallel to the bc plane.

Bis(acetyl-acetonato-?O,O')[copper(II)nickel(II)(0.31/0.69)]: a mixed-metal complex.

Project description:The title complex, [Cu(0.31)Ni(0.69)(C(5)H(7)O(2))(2)], was isolated from the reaction of bis-(N,N-dimethyamino-ethanol)copper(II) with bis-(acetyl-acetonato)nickel(II), which yielded crystals with mixed sites at the central metal position; the refined copper-nickel occupancy ratio is 0.31?(4):0.69?(4). Two acetyl-acetonate ligands, related by a centre of symmetry, are coordinated to the central metal atom in a square-planar configuration while the methyne C atoms of the acetyl-acetonate ligands, ca 3.02?Å away, are orthogonal to this plane at the metal site.

Bis(μ-1,2-bis-{[2-(2-pyrid-yl)-1H-imidazol-1-yl]meth-yl}benzene)bis-[bis-(thio-cyanato-κN)cadmium(II)].

Project description:The asymmetric unit of the binuclear title compound, [Cd(2)(NCS)(4)(C(24)H(20)N(6))(2)], contains one half-mol-ecule, consisting of one Cd(2+) cation, two half 1,2-bis-{[2-(2-pyrid-yl)-1H-imidazol-1-yl]meth-yl}benzene (L) ligands and two SCN(-) anions. The dimeric cyclic mol-ecule is completed by crystallographic inversion symmetry. The Cd(2+) cation is coordinated by two N atoms from two SCN(-) anions and four N atoms from two symmetry-related L ligands, exhibiting a distorted octrahedral coordination. A two-dimensional supra-molecular network stacked parallel to [210] is finally formed by linking these dimers through weak π-π stacking inter-actions between the pyridine rings and benzene rings of adjacent dimers, with a plane-to-plane distance of 3.36 (6) Å and a centroid-centroid distance of 3.67 (2) Å. One of the thio-cyanate S atoms is equally disordered over two positions.

5-[2-(4-Acetyl-oxyphen-yl)ethen-yl]benzene-1,3-diyl diacetate.

Project description:The title compound, C(20)H(18)O(6), was prepared from resveratrol {systematic name: 5-[(E)-2-(4-hy-droxy-phen-yl)ethen-yl]ben-z-ene-1,3-diol}, which can be isolated from grapes, through triacetyl-ation with using acetic anhydride in pyridine. The two benzene rings are approximately coplanar, making a dihedral angle of 6.64 (14)°, and the three acet-oxy group are located on the same side of the plane. The skeleton of the compound resembles a table with three legs. In the crystal, mol-ecules are linked via C-H⋯O interactions, forming inversion dimers. These dimers are further linked via C-H⋯O interactions, forming a three-dimensional structure.
