Synthesis and crystal structure of the copper(II) valerate complex with nicotinamide

A coordination compound of copper(II) valerate with nicotinamide, [CuL(C4H9COO)2]2 (I), has been synthesized, and its crystal structure has been determined by X-ray crystallography. The crystals of I are triclinic: a = 9.1245(9) Å, b = 9.8572(6) Å, c = 11.0944(9) Å, α = 73.51(1)°, β = 79.917(6)°, γ = 72.161(7)°, Z = 2, space group $$P\bar 1$$ . In the centrosymmetric binuclear molecule of I, the copper atoms (Cu...Cu′, 2.621 Å) are linked through four bidentate chelating valerate ligands (av., Cu-O 1.969 Å). The coordination polyhedron of the Cu atom is a tetragonal pyramid with the nitrogen atom of the pyridine ring in the apical position at a longer distance (Cu-N, 2.190 Å). © Pleiades Publishing, Inc., 2006

Synthesis and crystal structure of diaquadibenzoatobis(nicotinamide)nickel(II)

A coordination compound of nickel(II) benzoate with nicotinamide [Ni(C 6H5COO)2(L)2(H2O) 2] (I) (L is nicotinic acid amide) is synthesized and studied by IR spectroscopy. Its crystal structure is solved by X-ray crystallography. The crystals of compound I are monoclinic: a = 7.152 Å, b = 18.266 Å, c = 10.341 Å, β = 109.24°, V = 1275.4 Å3, Z = 2, space group P21/c. Structural units of a crystal of I are centrosymmetric octahedral complex molecules. The coordination environment of the Ni atom contains two O atoms (Ni-O(1) 2.066(2) Å) and two N atoms (Ni-N(1) 2.091(2) Å) of the monodentate-coordinated benzoate anions and nicotinamide molecules, respectively, as well as two O atoms of the H 2O molecules (Ni-O(1w) 2.110(2) Å). © Pleiades Publishing, Inc., 2006

Synthesis of copper and zinc chloride complexes with triand tetranitrofluorenones. Crystal and molecular structure of 2,4,5,7- tetranitrofluorenone

The complexes MLCl2 · nH2O and ML 2Cl2 · nH2O, where M = Cu(II), Zn and n = 1-4, were isolated and identified due to the reactions of Cu(II) and Zn (II) chlorides with 2,4,7-trinitrofluorene (L1), 2,4,7-trinitrofluorenone (L1a), and 2,4,5,7-tetranitrofluorene (L2). It was shown that, during complex formation, L1 and L2 were oxidized to fluorenones (L1a, L2a) and as neutral ligands formed 1:1 and 2:1 complexes with metal cations. A single crystal of tetranitrofluorenone (L2a) was isolated, and its crystal and molecular structure was determined. The complexes were studied by X-ray powder diffraction analysis, their spectral (IR and UV) characteristics were determined, and the structures for the complexes were proposed. © Pleiades Publishing, Ltd., 2010
