Bis(2-bromo-acetato-κO,O')(1,10-phenanthroline-κN,N')copper(II).

ABSTRACT: The two halves of the title compound, [Cu(C(2)H(2)BrO(2))(2)(C(12)H(8)N(2))], are related by twofold symmetry along the b axis through the central Cu(II) ion. The Cu(II) ion is coordinated by two symmetry-related N atoms from the 1,10-phenanthroline ligand and four O atoms from two 2-bromo-acetate ligands, showing a distorted octahedral geometry. Weak inter-molecular C-H⋯O inter-actions link neighbouring mol-ecules.

Project description:In the title complex, [Cu(C(2)HCl(2)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Cu(II) ion has a distorted square-pyramidal coordination geometry. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 1.994 (3) and 2.027 (3) Å] and two O atoms from dichloro-acetate ligands and a water mol-ecule [Cu-O = 1.971 (2) and 1.939 (2) Å]. One O atom from another dichloro-acetate ligand occupies the apical positon [Cu-O = 2.152 (3) Å]. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The crystal packing also exhibits weak inter-molecular C-H⋯O hydrogen bonds, π-π inter-actions [centroid-centroid distance = 3.734 (2) Å] and short inter-molecular Cl⋯Cl contacts [3.306 (2) and 3.278 (2) Å].

Project description:In the title compound, [Cu(C(2)H(2)IO(2))(2)(C(12)H(8)N(2))(H(2)O)], the Cu(II) ion is coordinated by two N atoms [Cu-N = 2.013 (4) and 2.024 (4) Å] from a 1,10-phenanthroline ligand and three O atoms [Cu-O = 1.940 (4)-2.261 (4) Å] from two carboxyl ligands and a water mol-ecule in a distorted square-pyramidal geometry. One iodo-acetate O atom [Cu-O = 2.775 (4) Å] completes the coordination to form a distorted octa-hedron. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed by π-π inter-actions between the 1,10-phenanthroline ligands into layers parallel to the ab plane. The crystal packing also exhibits short inter-molecular I⋯I contacts of 3.6772 (9) Å and weak C-H⋯O hydrogen bonds.

Project description:In the title compound, [Cu(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(H(2)O)], the coordination around the Cu(II) atom is square-pyramidal. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 2.008 (3) and 2.019 (3) Å] and two O atoms from 3-fluoro-benzoate ligands and a water mol-ecule [Cu-O = 1.950 (2) and 1.978 (2) Å]. One O atom from another 3-fluoro-benzoate ligand occupies the apical positon [Cu-O = 2.210 (2) Å]. Hydrogen bonds occur between coordinated water mol-ecules and benzoate ligands, while O-H⋯O, C-H⋯O, C-H⋯F and π-π stacking [centroid-centroid distance = 3.731 (2) Å] inter-actions consolidate the crystal packing.

Bis(2-methyl-benzoato-κO,O')(1,10'-phenanthroline-κN,N')copper(II).

Project description:In the title compound, [Cu(C(8)H(7)O(2))(2)(C(12)H(8)N(2))], the Cu(II) atom assumes a distorted octa-hedral coordination geometry, chelated by two N atoms from the 1,10'-phenanthroline ligand and four O atoms from two 2-methyl-benzoate anions. A significant Jahn-Teller distortion is observed with two axial Cu-O distances significantly longer than those in the equatorial CuO(2)N(2) plane. In the crystal, π-π stacking inter-actions, with centroid-centroid distances of 3.547 (3) or 3.728 (3) Å between the phenanthroline rings, form layers parallel to (011).
