ABSTRACT: 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).
Project description:In the title compound, [Cu(C(13)H(14)BrNO(3))(C(12)H(8)N(2))]·2H(2)O, the Cu(II) atom is penta-coordinated in a square-pyramidal geometry. The crystal packing is stabilized by O-H⋯O hydrogen bonds.
Project description:The title complex, [Sm(2)(C(3)H(5)O(2))(6)(C(12)H(8)N(2))(2)], is a dinuclear centrosymmetric mol-ecule, in which two crystallographically equivalent Sm atoms, separated by 3.9502 (2) Å, are bridged by four propanoate anions. Each Sm atom is coordinated by two N atoms from one chelating phenanthroline ligand and seven carboxylate O atoms from five propanoate anions, to form a distorted tricapped trigonal prism.
Project description: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].
Project description:In the title compound, [Zn(C(7)H(4)ClO(3))(2)(C(12)H(8)N(2))(H(2)O)], the Zn(II) cation is coordinated by two 4-chloro-2-salicylate anions, one 1,10-phenanthroline ligand and one water mol-ecule in a square-pyramidal coordination geometry; the Zn cation lies 0.4591 (11) Å from the basal plane. 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. Intra-molecular O-H⋯O hydrogen bonding is present.
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.
Project description:In the title dinuclear In(III) compound, [In(2)(SO(4))(3)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, each In(III) cation is coordinated by a 1,10-phenanthroline (phen) ligand, a water mol-ecule and three sulfate O atoms in a distorted InN(2)O(4) octa-hedral geometry. Three sulfate anions bridge two In(III) cations, forming the dinuclear entities. O-H⋯O and weak C-H⋯O hydrogen bonding is observed in the crystal structure. The crystal structure is further consolidated by π-π stacking between nearly parallel phen ring systems [dihedral angle = 4.2 (4)°], the centroid-centroid distance between benzene rings of adjacent phen ligands being 3.528 (9) Å.
Project description:In the mononuclear title complex, [Gd(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], the Gd atom is in a pseudo-bicapped square-anti-prismatic geometry formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and by six O atoms, four from two 2,6-dihy-droxy-benzoate (DHB) ligands and the other two from a nitrate anion. π-π stacking inter-actions between phen-DHB [centroid-centroid distances = 3.5334 (18) and 3.8414 (16) Å] and phen-phen [face-to-face separation = 3.4307 (17) Å] ligands of adjacent complex molecules stabilize the crystal structure. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.
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.
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.
Project description:In the title compound, [Cu(C(2)H(3)O(3))(C(12)H(8)N(2))(2)]NO(3), the Cu(II) atom is coordinated by two phenanthroline (phen) ligands and one carboxyl-O atom of a hy-droxy-acetate anion in a distorted square-pyramidal geometry. The hy-droxy group of the hy-droxy-acetate ligand links with the counter NO(3) (-) anion via a pair of bifurcated O-H⋯O hydrogen bonds. The centroid-centroid distance of 3.5676 (14) Å between benzene rings of parallel phen ligands of adjacent mol-ecules suggests the existence of π-π stacking. Weak inter-molecular C-H⋯O hydrogen bonding is also present in the crystal structure.
