A new polymorph of aqua-bis-(1,10-phenanthroline-?(2) N,N')copper(II) dinitrate.

ABSTRACT: The title mol-ecule, [Cu(C12H8N2)2(H2O)](NO3)2, is a new polymorph of a compound which up to now has been reported to crystallize space groups in C2/c and Cc. The crystal studied was twinned by non-merohedry (final BASF factor of 0.40043) with the structure being solved and refined in P-1. The Cu(II) atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and an O atom from a water mol-ecule in an approximate trigonal-bipyramidal geometry. Discrete entities of one cation and two nitrate anions are formed by water-nitrate O-H?O hydrogen bonds. The components are further assembled into a three-dimensional network by C-H?O hydrogen bonds.

Project description:The title complex, [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](NO(3))(2)·2H(2)O, contains a dimeric [Cu(2)(C(4)H(5)O(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) dication with two five-coordinated Cu(II) ions linked by two methacrylate ions in a syn-syn bridging arrangement. The dication possesses pseudo-twofold rotational symmetry. The penta-coordination of each Cu(II) ion has a distorted square-pyramidal geometry, with two N donors from a phenanthroline ligand and two carboxyl-ate O atoms occupying basal sites and the apical position being occupied by a water mol-ecule. In the crystal packing, mol-ecules are linked to form a three-dimensional framework by O-H?O and C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distances of 3.6039?(15), 3.5301?(15), 3.6015?(15), 3.6496?(15) and 3.6858?(15)?Å].

A second polymorph of aqua-(2,9-di-methyl-1,10-phenanthroline-κN,N')bis-(formato-κO)copper(II).

Project description:A new monoclinic polymorphic form of the title compound, [Cu(HCO(2))(2)(C(14)H(12)N(2))(H(2)O)], is described. It differs from the first ortho-rhom-bic polymorph [Pan, Lin & Zheng (2005 ▶). Z. Kristallogr. New Cryst. Struct.220, 495-496] in the deviation of the Cu atom relative to the plane of the 2,9-dimethyl-1,10-phenanthroline (dmp) ligand. In the present structure, the Cu atom is shifted from the mean plane of the dmp ligand by only 0.005 (1) Å, compared with 0.318 (6) Å in the ortho-rhom-bic form. Hydrogen-bonding and π-π stacking inter-actions (mean inter-planar distance of 3.59 Å in the title compound) in the two different polymorphs are both essential to the supra-molecular assembly.

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.

?-Decane-dioato-bis-[aqua-bis-(1,10-phenanthroline-?N,N')manganese(II)] dinitrate-sebacic acid-water (1/1/2).

Project description:In the title complex, [Mn(2)(C(10)H(16)O(4))(C(12)H(8)N(2))(4)(H(2)O)(2)](NO(3))(2)·C(10)H(18)O(4)·2H(2)O, the asymmetric unit contains one-half of the centrosymmetric dinuclear complex cation, one uncoordinated water molecule, one-half of a free sebaic acid (decanedioic acid) molecule that is also completed by inversion symmetry, and one disordered nitrate anion [occupancy ratio 0.454?(4):0.544?(6)]. The Mn(II) atoms are each octa-hedrally surrounded by four N atoms from two 1,10-phenanthroline (phen) ligands, one O atom from one carbonyl group of the bridging sebacate ligand and one O atom of a water mol-ecule. The crystal structure is stabilized by intermolecular O-H?O hydrogen bonds.

Bis(N'-benzoyl-pyridine-4-carbohydrazide)(1,10-phenanthroline)copper(II) dinitrate.

Project description:In the title complex, [Cu(C(13)H(11)N(3)O(2))(2)(C(12)H(8)N(2))](NO(3))(2), the Cu(II )atom (site symmetry 2) is coordinated by four N atoms from one 1,10-phenanthroline and two hydrazine ligands, respectively. The hydrazine ligands coordinate to the Cu(II)atom by a pyridine N atom. These four atoms form a slightly distorted square-planar N(4) donor set. In the packing, two additional Cu?O inter-actions occur [Cu?O = 2.462?(2)?Å], resulting in a typical Jahn-Teller-distorted octahedral environment around the Cu atom. N-H?O hydrogen bonds result in a three-dimensional network. The O atoms of the anion are disordered over two positions in a 0.68?(2):0.32?(2) ratio.

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 ?-? stacking inter-actions between symmetry-equivalent anti-parallel non-nitro-gen aromatic rings, with inter-planar distances of 3.543?(2)?Å.
