Dichlorido[1-(1,10-phenanthrolin-2-yl)-2-pyridone]copper(II).

ABSTRACT: In the title mononuclear complex, [CuCl(2)(C(17)H(11)N(3)O)], the Cu(II) ion is in a distorted square-pyramidal coordination environment. The crystal structure is stabilized by various π-π stacking inter-actions in which the benzene ring, a pyridine ring and the five-membered CuN(2)C(2) ring are involved. The centroid-centroid distances range from 3.5631 (15) to 3.5666 (16) Å.

Dichlorido[1-(1,10-phenanthrolin-2-yl)-2-pyridone]cadmium(II).

Project description:In the title mononuclear complex, [CdCl(2)(C(17)H(11)N(3)O)], the Cd(II) ion assumes a distorted trigonal-bipyramidal coordination geometry. The pyridone plane is twisted out of the 1,10-phenanthroline mean plane by 43.8?(3)°. In the crystal structure, short inter-molecular distances [3.627?(4)-3.671?(4)?Å] between the centroids of the six- and five-membered Cd-containing rings suggest the existence of ?-? inter-actions, which link the mol-ecules into stacks along the a axis.

Crystal structure of di-?-hydroxido-bis-{aqua-[ethyl (1,10-phenanthrolin-3-yl)phospho-nato-?2 N,N']copper(II)} hepta-hydrate.

Project description:In the title compound, [Cu2(OH)2{C12H7N2(PO3C2H5)}2(H2O)2]·7H2O, two Cu2+ cations are bridged by two hydroxide groups, forming a centrosymmetric binuclear complex. Each Cu2+cation is further coordinated by the N atoms of a bidentate ethyl (1,10-phenanthrolin-3-yl)phospho-nate anion and a water mol-ecule in a square-pyramidal geometry. In the crystal, a network of O-H?O hydrogen bonds involving the P(O)(O-)(OEt) groups, bridging hydroxyl groups, coordinated and uncoordinated water mol-ecules generates a three-dimensional supra-molecular structure. The ethyl group exhibits disorder and was modelled over three sites with occupancies of 0.455, 0.384 and 0.161.

Project description:In the polymeric title compound, [Cd(C(4)H(2)O(4))(C(19)H(12)N(4)O)(2)](n), the Cd(II) centre is eight-coordinated within an N(4)O(4) donor set derived from two chelating 4-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)phenol ligands and two asymmetrically chelating carboxyl-ate residues of bridging fumarate dianions.
