Bis{2-[bis-(2-hy-droxy-eth-yl)amino]-acetato-κO,N,O'}zinc(II).

ABSTRACT: In the crystal structure of the zinc(II) complex of bicine, [Zn(C(6)H(12)NO(4))(2)], the deprotonated amino acid O,N,O'-chelates to the metal atom through a carboxyl-ate O atom, a hy-droxy O atom and the N atom, the three atoms occupying fac positions of the distorted octa-hedron surrounding the metal atom. The metal atom lies on a center of inversion. The uncoordinated carboxyl-ate O atom is hydrogen bonded to the hy-droxy groups of adjacent mol-ecules, these two hydrogen bonds leading to the formation of a three-dimensional network.

Project description:The dinuclear title complex, [Sm(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, contains two Sm(III) atoms, six deprotonated p-hy-droxy-phenyl-acetic acid (PAA) mol-ecules, two 4,4'-bipyridine (bipy) mol-ecules, two coordinated water mol-ecules and one solvent water molecule. Each Sm(III)ion is nine-coordinated by seven O atoms from four PAA ligands, one water O atom and one N atom from a bipy ligand in a distorted geometry. The PAA ligands are coordinated to the Sm(III) ion in bridging and bridging tridentate modes. The asymmetric unit also contains one uncoordinated water mol-ecule. The occurrence of numerous O-H⋯O and O-H⋯N hydrogen bonds involving coordinated and non-coordinated water mol-ecules builds up an intricate three-dimensional network.

trans-Bis(ethyl-enediamine)-bis-{2-[N-(2-hy-droxy-eth-yl)oxamoyl-amino]-benzoato}nickel(II).

Project description:The title mononuclear Ni(II) complex, [Ni(C(11)H(11)N(2)O(5))(2)(C(2)H(8)N(2))(2)], is built up by inversion symmetry associated with the central Ni atom. The ethyl-enediamine ligands are non-planar. The r.m.s. deviation from the mean plane of the five-membered Ni-ethyl-amine chelate ring plane is 0.1945 Å. In the crystal structure, complex mol-ecules are linked to each other via N-H⋯O and O--H⋯O hydrogen bonding through translation symmetry along the b and c axes, resulting in an extended supra-molecular network.

Project description:In the polymeric title complex, {[Ce(C(8)H(7)O(3))(3)(H(2)O)(2)]·2C(10)H(8)N(2)·H(2)O}(n), the Ce(III) ion is coordinated by ten O atoms from four 2-(4-hy-droxy-phen-yl)acetate (HPAA) ligands and two water mol-ecules.

In the crystal, O-H⋯O and O-H⋯N hydrogen bonds link mol-ecules into a three-dimensional network.

(2-Hy-droxy-acetato-κO)bis-(1,10-phenan-throline-κN,N')copper(II) nitrate.

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.

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.
