Bis(4'-hy-droxy-biphenyl-4-carboxyl-ato-κO)(1,10-phenanthroline-κN,N')zinc.

ABSTRACT: In the title compound, [Zn(C(13)H(9)O(3))(2)(C(12)H(8)N(2))], the Zn(II) atom is located on a twofold rotation axis and has a distorted tetra-hedral coordination with two N atoms from the phenanthroline ligand arranged around the twofold axis and two O atoms from two symmetry-related 4'-hy-droxy-biphenyl-4-carboxyl-ate ligands. The mol-ecules are linked by O-H⋯O hydrogen bonds, forming a chain developing parallel to [101].

The benzene rings of the anions are involved in π-π stacking. The centroid-centroid distance between parallel benzene rings of adjacent mol-ecules is 3.9017 (17) Å, and the centroid-centroid distance between benzene and pyridine rings of adjacent mol-ecules is 3.584 (2) Å.

Triaqua-(1,10-phenanthroline-κN,N')(sulfato-κO)zinc(II).

Project description:The Zn(II) atom in the title compound, [Zn(SO(4))(C(12)H(8)N(2))(H(2)O)(3)], is coordinated by one O atom from a sulfate dianion, two N atoms from a 1,10-phenanthroline mol-ecule and three water O atoms in an octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond occurs. Inter-molecular O-H⋯O hydrogen bonds generate a layer structure parallel to (001). There are weak C-H⋯O inter-actions within the layers.

Bis[2-(4-hy-droxy-phen-yl)acetato-κO]bis-(1,10-phenanthroline-κN,N')cadmium penta-hydrate.

Project description:In the title compound, [Cd(C(8)H(7)O(3))(2)(C(12)H(8)N(2))(2)]·5H(2)O, the Cd(II) ion is six-coordinated by two carboxylate O atoms of monodentate 2-(4-hy-droxy-phen-yl)acetate ligands and by four N atoms from two chelating 1,10-phenantroline ligands in a distorted trigonal-prismatic geometry. O-H⋯O hydrogen bonds between water mol-ecules and the complex mol-ecules result in the formation of a three-dimensional network. Four water mol-ecules act as single acceptors and double donors while the fifth water mol-ecule is involved as a single acceptor and single donor in an O-H⋯O inter-action and as a donor in an O-H⋯π inter-action.

(Croconato-κO,O')bis-(1,10-phenanthroline-κN,N')zinc(II).

Project description:In the title compound, [Zn(C(5)O(5))(C(12)H(8)N(2))(2)], the Zn atom is in a slightly distorted octa-hedral environment. The mol-ecule lies across a twofold rotation axis, around which two 1,10-phenanthroline ligands are arranged. There are short contacts between the 1,10-phenanthroline groups and the O atoms of the croconate ligand, which probably stabilize the crystal structure via weak C-H⋯O interactions.

Project description:In the crystal structure of the title compound, [Zn(C(7)H(10)O(4))(C(12)H(8)N(2))(2)]·6H(2)O, the Zn(II) atom is coordinated by two carboxyl-ate O atoms of a mono-bidentate chelating pimelate anion (pimelic acid is hepta-nedioic acid) and four N atoms of two phenanthroline ligands, forming a considerably distorted octa-hedral ZnN(4)O(2) coordination geometry. The complexes are assembled into a three-dimensional network via C-H⋯O, C-H⋯π and π-π inter-actions. The mean inter-planar distance between adjacent phenanthroline ligands is 3.399 (2) Å.

Project description:In the mononuclear title complex, [Nd(C(7)H(5)O(4))(2)(NO(3))(C(12)H(8)N(2))(2)], the Nd(III) atom is in a distorted bicapped square-anti-prismatic geometry formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, four O atoms from two 2,6-dihy-droxy-benzoate (DHB) ligands and two O atoms from a nitrate anion. π-π stacking inter-actions between the phen and DHB ligands of adjacent complexes [centroid-centroid distances = 3.520 (6) and 3.798 (6) Å] stabilize the crystal structure. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.

Aqua-(imino-diacetato-κO,N,O')(1,10-phenanthroline-κN,N')zinc(II) sesquihydrate.

Project description:The imino-diacetate dianion in the title compound, [Zn(C(4)H(5)NO(4))(C(12)H(8)N(2))(H(2)O)]·1.5H(2)O, chelates to the Zn(II) center with its N and two O atoms. The metal atom is also chelated by the N-heterocycle and coordinated by one water molecule, leading to a distorted octahedral environment. The dianion, and coordinated and uncoordinated water mol-ecules inter-act through O-H⋯O hydrogen bonds, generating a three-dimensional network. One of the two uncoordinated water mol-ecules has half-site occupancy. The crystal studied was a non-merohedral twin with a 15% twin component.

Project description:In the title complex, [Cu(C(17)H(15)NO(5))(C(12)H(8)N(2))]·2H(2)O, the central Cu(II) ion is five-coordinate, bound to one N atom and two O atoms from the Schiff base ligand and by two N atoms from a 1,10-phenanthroline ligand in a distorted square-pyramidal configuration. In the crystal, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds form a two-dimensional network parallel to (001).

Bis(μ-2,4-dihy-droxy-benzoato-κO:O')bis-[aqua-(2,4-dihy-droxy-benzoato-κO)(1,10-phenanthroline-κN,N')cadmium(II)].

Project description:In the title centrosymmetric dimeric Cd(II) complex, [Cd(2)(C(7)H(5)O(4))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)], the Cd(II) cation is coord-inated by a bidentate phenanthroline (phen) ligand, three dihy-droxy-benzoate (dhba) anions and one water mol-ecule in a distorted CdN(2)O(4) octa-hedral geometry. Among the dhba anions, two anions bridge two Cd(II) cations to form the dimeric complex with significant different Cd-O bond distances of 2.2215 (19) and 2.406 (2) Å. The centroid-centroid distance of 3.4615 (19) Å between two nearly parallel benzene rings of the dhba and phen ligands coordinating to the same Cd(II) cation indicates the existence of intra-molecular π-π stacking in the complex. Extensive O-H⋯O hydrogen bonding and inter-molecular weak C-H⋯O hydrogen bonding help to stabilize the crystal structure. One hy-droxy group of the monodentate dhba ligand is disordered over two sites with a site-occupancy ratio of 0.9:0.1.
