Aqua-(hippurato)bis-(1,10-phenanthroline)cobalt(II) nitrate monohydrate.

ABSTRACT: In the title compound, [Co(C(9)H(8)NO(3))(C(12)H(8)N(2))(2)(H(2)O)]NO(3)·H(2)O, the Co(II) atom is six-coordinated by a carboxylate O atom of the hippurate (Hc) anion, a water O atom and four N atoms from two 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The uncoordinated O atom of the hippuric acid anion is involved in an intra-molecular hydrogen bond to the coordinated water mol-ecule. The crystal packing is stabilized by inter-molecular O-H?O hydrogen bonds involving the Hc anions, the coordinated water mol-ecule, the nitrate anion and the uncoordinated water mol-ecule.

Project description:The title compound, [Co(C(12)H(8)N(2))(H(2)O)(4)](2)[Co(H(2)O)(6)](C(11)H(7)O(8))(2)·4H(2)O, was obtanied by the reaction of cobalt acetate with 3,5-bis-(carb-oxy-meth-oxy)benzoic acid and 1,10-phenanthroline. The asymmetric unit contains one tetra-aqua-(1,10-phenanthroline)cobalt(II) cation, one half of a hexa-aqua-cobalt(II) cation that is completed by inversion symmetry, one 3,5-bis-(carboxyl-atometh-oxy)benzoate trianion and two lattice water mol-ecules. The two Co(II) atoms each show a slightly distorted octa-hedral coordination (CoO(6) and CoO(4)N(2)). The cations, anions and lattice water mol-ecules are linked by an intricate network of O-H?O hydrogen bonds into a three-dimensional structure.

Project description:In the title mononuclear complex, [Cu(NO(3))(C(12)H(10)N(4))(H(2)O)]NO(3), the Cu(II) ion assumes a distorted square-pyramidal geometry. There is a π-π stacking inter-action between the five-membered ring containing the Cu atom and a pyridine ring of a neighboring complex [centroid-centroid distance = 3.567 (2) Å and a perpendicular distance of 3.394 Å]. The crystal structure also contains inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, linking cations and anions. In addition, there is a short inter-molecular contact [2.784 (6) Å] between an O atom of the coordinated nitrate group and its symmetry-related atom.

Project description:In the title compound, [Cd(C(6)H(4)O(8)S(2))(C(12)H(8)N(2))(2)(H(2)O)]·H(2)O, each Cd(II) ion is coordinated by four N atoms [Cd-N = 2.310 (7)-2.341 (7) Å] from two 1,10-phenanthroline ligands, one O atom [Cd-O = 2.300 (6) Å] from a 4,5-dihydroxy-benzene-1,3-disulfonate ligand and one aqua O atom [Cd-O = 2.288 (7) Å] in a distorted octa-hedral geometry. The crystal packing exhibits inter-molecular O-H⋯O and C-H⋯O hydrogen bonds and π-π inter-actions evidenced by relatively short distances [3.525 (5)-3.937 (6) Å] between the centroids of the six-membered rings of neighbouring mol-ecules.
