(2-Formyl-6-methoxy-phenolato-?O,O)(perchlorato-?O)(1,10-phenanthroline-?N,N')copper(II).

ABSTRACT: In the title mol-ecule, [Cu(C(8)H(7)O(3))(ClO(4))(C(12)H(8)N(2))], the Cu(II) ion is five-coordinated by two N atoms [Cu-N = 1.995?(3) and 2.022?(3)?Å] from a 1,10-phenanthroline ligand, two O atoms [Cu-O = 1.908?(2) and 1.927?(2)?Å] from an o-vanillin ligand and one O atom [Cu-O = 2.510?(3)?Å] from a perchlorate anion in a distorted square-pyramidal geometry. Three O atoms of the perchlorate anion are rotationally disordered between two orientations, with occupancies of 0.525?(13) and 0.475?(13). In the crystal structure, two mol-ecules related by a centre of symmetry are paired in such a way that the phenolate O atom from one mol-ecule completes the distorted octa-hedral Cu coordination in another mol-ecule [Cu?O = 2.704?(2)?Å].

Diaqua-bis-(perchlorato)(1,10-phenanthroline)copper(II).

Project description:In the title compound, [Cu(ClO(4))(2)(C(12)H(8)N(2))(H(2)O)(2)], the Cu(II) atom is coordinated in a square-planar fashion by the two N atoms of a chelating 1,10-phenanthroline ligand and by two water mol-ecules trans to the N atoms. The coordination sphere of the metal atom is augmented by O atoms of two weakly bonded perchlorate anions, thus yielding a strongly distorted CuN(2)O(4) octa-hedral environment. The crystal packing is stabilized by O-H⋯O hydrogen bonds between the water mol-ecules and the perchlorate anions. In addition, the organic mol-ecules are associated by π-π stacking inter-actions between symmetry-equivalent anti-parallel non-nitro-gen aromatic rings, with inter-planar distances of 3.543 (2) Å.

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.
