Bis[2-(methyl-amino)-troponato]copper(II).

ABSTRACT: In the title compound, [Cu(C(8)H(8)NO)(2)], a strictly square-planar geometry about the Cu(II) metal atom is observed. Substitution of an O atom with a methyl-functionalized N atom does not significantly alter the bond distances and angles in the copper(II) complex when compared with a similar bis-(troponato)copper(II) complex. ?-? stacking is observed between the tropolone rings, with inter-planar distances of 3.5039?(16) and 3.2933?(15)?Å, respectively. Additional stabilisation of the structure is accomplished through C-H?O hydrogen-bonding interactions.

{3-[Bis(2-pyridyl-methyl-?N)amino-?N]propanol}bis-(nitrato-?O)copper(II).

Project description:In the title compound, [Cu(NO(3))(2)(C(15)H(19)N(3)O)], the Cu(II) ion is coordinated by the N atoms of the tetra-dentate 3-[bis-(2-pyridyl-meth-yl)amino]-propanol ligand and two O atoms from two monodentate nitrate anions, resulting in a distorted square-pyramidal environment. An inter-molecular O-H?O hydrogen-bonding inter-action between the free hy-droxy group of the ligand and a nitrate O atom of an adjacent complex unit, gives a chain structure which extends across the (101) planes.

?-(2,6-Bis{[3-(di-methyl-amino)-prop-yl]imino-meth-yl}-4-methyl-phenolato)-?-hydroxido-bis-[(thio-cyanato-?N)copper(II)].

Project description:In the title compound, [Cu2(C19H31N4O)(OH)(NCS)2], the mol-ecular structure of the dinuclear complex reveals two penta-coordinated Cu(II) ions, which are bridged by the phenolate O atom of the ligand and by an exogenous hydroxide ion. The bridging atoms occupy equatorial positions in the coordination sphere of the metal atoms and complete the equatorial coordination planes with two ligand N atoms, the apical positions being occupied by thio-cyanate N atoms. The crystal structure also features ?-? stacking inter-actions involving the benzene rings with a centroid-centroid distance of 3.764?(4)Å. The crystal studied was a non-merohedral twin, with a refined BASF value of 0.203?(2).

Project description:In the title compound, [Cu(C(4)H(12)N(2)O)(2)](NO(3))(2), the central Cu(II) atom has a distorted octa-hedral coordination geometry and is surrounded by four N atoms and two O atoms from the two inversion-related 2-(2-amino-ethyl-amino)-ethanol ligands. In the crystal, mol-ecules are held together by inter-molecular O-H?O and N-H?O hydrogen bonds, leading to the formation of a three-dimensional network.

Bis(isonicotinamide-?N)bis-(4-methyl-benzoato-?O)copper(II) dihydrate.

Project description:In the centrosymmetric title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)]·2H(2)O, the Cu(II) ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-methyl-benzoate anion, one isonicotinamide (INA) ligand and one uncoordinated water mol-ecule; all the ligands are monodentate. The two O and the two N atoms around the Cu(II) ion form a slightly distorted square-planar arrangement. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 13.86?(9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 86.08?(5)°. The uncoordinated water mol-ecules are linked to the INA ligands by O-H?O hydrogen bonds. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.
