Aqua[N-(2,5-dihydroxybenzyl)imino-diacetato]copper(II).

ABSTRACT: The title complex, [Cu(C(11)H(11)NO(6))(H(2)O)], contains a Cu(II) atom in a distorted square-pyramidal geometry. The metal centre is coordinated in the basal sites by one water mol-ecule and two carboxyl-ate O atoms and one N atom of the tetra-dentate ligand [Cu-O range, 1.9376?(11)-1.9541?(12), Cu-N, 1.9929?(12)?Å] while the apical site is occupied by a hydro-quinone O donor atom [Cu-O, 2.3746?(12)?Å]. Inter-molecular hydrogen bonding inter-actions involving both hydro-quinone hydr-oxy groups and the coordinated water as donors give a three-dimensional framework structure.

Project description:In the title compound, [Cu(C(4)H(5)O(4))(H(2)O)](n), the imino-diacetate (ida) ligands link the Cu(II) atoms into polymeric zigzag chains running along [010]. Each Cu(II) ion is five-coordinated in a distorted square-pyramidal geometry by one N and two O atoms from an ida ligand, one O atom from the neighbouring ida ligand and one water O atom. In the crystal, the polymeric chains are held together via inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.

Aqua-[4-(hy-droxy-imino-meth-yl)pyridine-?N](imino-diacetato-?O,N,O')copper(II).

Project description:In the title complex, [Cu(C(4)H(5)NO(4))(C(6)H(6)N(2)O)(H(2)O)], conventionally abbreviated Cu(IDA)(4-OXPy)(H(2)O), where IDA is imino-diacetate and 4-OXPy is 4-(hy-droxy-imino-meth-yl)pyridine, the Cu(II) atom exhibits a distorted square-pyramidal coordination geometry, which is constructed from two O atoms and one N atom from a IDA ligand, one N atom from 4-OXPy ligand and one O atom from water. This mol-ecule looks like a space shuttle, the IDA ligand is its empennage (tail), and the 4-OXPy ligand is its airframe. The complexes are linked into two-dimensional supra-molecular layers parallel to (100) by three pairs of O-H?O hydrogen bonds. Two pairs of N-H?O hydrogen bonds further connect these supra-molecular layers, forming a three-dimensional supra-molecular network.

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 compound, [CaCo(3)(C(4)H(5)NO(4))(3)(OH)(3)O(H(2)O)(5)]·2.54H(2)O, the Co atom is octa-hedrally coordinated by one imino-diacetate (ida) dianion as a facial O,N,O'-tridentate ligand, two ?(3)-OH groups and one ?(3)-O ligand, forming an partial Co(3)O(4) cubane cluster. This unit coordinates to a Ca(II) cation in an O,O',O''-tridentate fashion, generating a distorted CaCo(3)O(4) cubane-type cluster. The Ca-?(3)-O distances [2.429?(5)-2.572?(6)?Å] are much longer than the Co-?(3)-O bonds [1.895?(5)-1.941?(5)?Å]. The Ca(II) cation is also coord-inated by five water mol-ecules with Ca-O distances in the range 2.355?(6)-2.543?(6)?Å. There are three additional uncoordinated water mol-ecules in the asymmetric unit, the occupancy of which refined to 0.54?(3). In H(2)O (or D(2)O), the title complex hydrolyses to Ca(2+) (aq) cations and [Co(3)(ida)(3)(?(2)-OH)(3)(?(3)-O)](2-) anions.
