(Acetylacetone isonicotinoylhydrazonato-κ3 O,N′,O′)dioxidovanadate(V) monohydrate

چکیده
The hydrazone anion in the title compound, [V(C(11)H(12)N(3)O(2))O(2)]·H(2)O, is zwitterionic as its pyridyl N atom is protonated; the O, N and O' atoms span the axial-equatorial-axial positions of the trigonal-bipyramidal coord-in-ation polyhedron of the metal atom. All non-H atoms lie on a crystallographic mirror plane apart from the oxide ligands, which are related by mirror symmetry. The pyridinium N atom acts as a hydrogen-bond donor to the solvent water mol-ecule, which is in turn a hydrogen-bond donor to the both oxide ligands. These hydrogen-bonding inter-actions give rise to a three-dimensional network motif.

The tridentate Schiff base ligand in the title compound, [V(C(16)H(14)N(2)O(3))(CH(3)O)O], has its O, N and O' atoms spanning three basal positions of the square-based-pyrimidally V(V) atom. The fourth basal site is occupied by a methoxo ligand, which results from a deprotonated methanol solvent molecule, and the oxido ligand occupies the apical position. The hy-droxy H atom forms an intra-mole...

The title compound, {[Cu(C(12)H(6)N(2)O(4))(H(2)O)(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The Cu(2+) ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2'-bipyridine-3,3'-dicarboxyl-ate bridging ligand in a sligthly distorted octa-hedral environment. The 2,2-bipyridine-3,3'-dicarboxyl-ate bridges link the Cu(2+) ions into chains along ...

In the title compound, {[Cu(C(7)H(3)NO(4))(H(2)O)(3)]·H(2)O}(n), the Cu(II) ion is bonded to three water mol-ecules, one N,O-bidentate pyridine-2,3-dicarboxyl-ate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO(5) octa-hedral geometry. The bridging ligand results in an infinite chain. A network of O-H⋯O hydrogen bonds helps to establish the crystal structure.

The imino-diacetate dianion in the title compound, [Co(C(4)H(5)NO(4))(C(12)H(8)N(2))(H(2)O)]·H(2)O, chelates to the cobalt(II) atom, its N and two O atoms occupying the fac sites of the distorted octa-hedron around the metal atom. The metal atom is also chelated by the N-heterocycle. The dianion, and coordinated and uncoordinated water mol-ecules inter-act through hydrogen bonds, generating a l...
