A monoclinic polymorph of di-μ-oxido-bis-({2-[2-(methyl-amino)ethyl-imino-methyl]phenolato-κN,N',O}oxidovanadium(V)).

ABSTRACT: A new monoclinic polymorph of the title compound, [V(2)(C(10)H(13)N(2)O)(2)O(4)], which is a centrosymmetric dimer, crystallizes in space group P2(1)/c, whereas the previously known polymorph crystallizes in the ortho-rhom-bic space group Pbca [Mokry & Carrano (1993 ▶). Inorg. Chem.32, 6119-6121]. Each V(V) atom is six-coordinated by one oxide group, two N atoms and one O atom from the Schiff base ligand, and by two additional bridging O atoms. The two methyl-ene groups are each disordered over two sites, with occupancy factors of 0.776 (14) and 0.224 (14). In the crystal structure, there are C-H⋯O hydrogen bonds and C-H⋯π inter-actions between the dimers.

Project description:In the title centrosymmetric dinuclear dioxidovanadium(V) complex, [V(2)(C(13)H(19)N(2)O(3))(2)O(4)], the V(V) ion is coordinated by an N,N',O-tridendate 2-eth-oxy-6-{[2-(2-hy-droxy-ethyl-amino)-ethyl-imino]-meth-yl}phenolate ligand and three oxide O atoms, forming a distorted cis-VN(2)O(4) octa-hedral geometry. The bridging O atoms show one short and one long bond to their two attached V(V) atoms. The dihedral angle between the benzene ring of the ligand and the V(2)O(2) plane is 75.2 (3)°. The deviation of the V(V) ion from the plane defined by the three donor atoms of the tridentate ligand and one bridging oxide O atom is 0.337 (2) Å towards the terminal oxide O atom. Two N-H⋯O hydrogen bonds help to establish the conformation of the dimer. In the crystal, the complex mol-ecules are linked by O-H⋯O hydrogen bonds, forming [100] chains.

Bis[2-(hy-droxy-imino-meth-yl)phenolato]nickel(II): a second monoclinic polymorph.

Project description:The title compound, [Ni(C(7)H(6)NO(2))(2)], (I), is a second monoclinic polymorph of the compound, (II), reported by Srivastava et al. [Acta Cryst. (1967), 22, 922] and Mereiter [Private communication (2002) CCDC refcode NISALO01]. The bond lengths and angles are similar in both structures. The mol-ecule in both structures lies on a crystallographic inversion center and both have an inter-nal hydrogen bond. The title compound crystallizes in the space group P2(1)/c (Z = 2), whereas compound (II) is in the space group P2(1)/n (Z = 2) with a similar cell volume but different cell parameters. In both polymorphs, mol-ecules are arranged in the layers but in contrast to the previously published compound (II) where the dihedral angle between the layers is 86.3°, in the title polymorph the same dihedral angle is 29.4°. The structure of (I) is stabilized by strong intra-molecular O-H⋯O hydrogen bonding between the O-H group and the phenolate O atom.

Project description:The V(IV) atom in the title complex, [V(C(11)H(13)BrClN(2)O)(C(5)H(7)O(2))O], is six-coordinated by one phenolate O, one imino N and one amino N atom of the tridentate anionic Schiff base ligand, by one oxide O atom, and by two O atoms of an acetyl-acetonate anion, forming a distorted cis-VN(2)O(4) octa-hedral coordination geometry. The deviation of the V atom from the plane defined by the three donor atoms of the Schiff base ligand and one O atom of the acetyl-acetone ligand towards the oxide O atom is 0.256 (2) Å.

Crystal structure of [2-({[2-(dimethylamino-κN)ethyl]imino-κN}methyl)phenolato-κO](1,10-phenanthroline-κ2N,N′)copper(II) perchlorate

Project description:The asymmetric unit of the [Cu(L)(phen)](ClO4) complex {L= 2-[(2-dimethylaminoethylimino)methyl]phenol} and phen = 1,10-phenanthroline) contains two crystallographically independent molecules. It consists of alternating layers of he two types of molecules, which stack along the c axis. The title compound, [Cu(C11H15N2O)(C12H8N2)]ClO4 or [Cu(L)(phen)](ClO4) {where L refers to the deprotonated form of 2-[(2-dimethylaminoethylimino)methyl]phenol} and phen is 1,10-phenanthroline) is a mononuclear mixed ligand copper(II) complex. The CuII atom is coordinated by two N and one O atoms of the tridentate Schiff base ligand (HL) and two N atoms of the 1,10-phenanthroline ligand, resulting in a five-coordinate complex. The asymmetric unit of the title complex contains two crystallographically independent complex cations (a and b) with a slightly different geometry around the CuII ion. The value of the trigonality index τ, indicates that in both cations a and b, the CuII atoms display a square-pyramidal distorted trigonal–bipyramidal (SPDTBP) geometry, although the distortion is greater for cation a.

μ-(2,6-Bis{[3-(di-methyl-amino)-prop-yl]imino-meth-yl}-4-methyl-phenolato)-μ-hydroxido-bis-[(thio-cyanato-κN)copper(II)].

Project description:In the title compound, [Cu2(C19H31N4O)(OH)(NCS)2], the mol-ecular structure of the dinuclear complex reveals two penta-coordinated Cu(II) ions, which are bridged by the phenolate O atom of the ligand and by an exogenous hydroxide ion. The bridging atoms occupy equatorial positions in the coordination sphere of the metal atoms and complete the equatorial coordination planes with two ligand N atoms, the apical positions being occupied by thio-cyanate N atoms. The crystal structure also features π-π stacking inter-actions involving the benzene rings with a centroid-centroid distance of 3.764 (4)Å. The crystal studied was a non-merohedral twin, with a refined BASF value of 0.203 (2).

Bis{4-chloro-6-formyl-2-[(E)-2-(1H-imidazol-4-yl-κN)ethyl-imino-methyl-κN]phenolato-κO}nickel(II).

Project description:In the title compound, [Ni(C(13)H(11)ClN(3)O(2))(2)], the Ni(II) atom is located on a twofold rotation axis and is six-coordinated by four N atoms and two phenolate O atoms from the two equal Schiff base ligands in a distorted octa-hedral coordination geometry. The complex mol-ecules are connected by C-H⋯Cl, C-H⋯O and N-H⋯O hydrogen bonds.

A triclinic polymorph of dichlorido(2-{[2-(isopropyl-ammonio)-eth-yl]imino-methyl-κN}-5-meth-oxy-phenolato-κO(1))zinc.

Project description:The title compound, [ZnCl(2)(C(13)H(20)N(2)O(2))], was first reported in the monoclinic space group P2(1)/n [Han et al. (2010 ▶). Acta Cryst. E66, m469]. This investigation reveals a triclinic polymorph in the space group P-1 with an asymmetric unit that contains two independent mol-ecules of the mononuclear zinc(II) complex. In each mol-ecule, the Zn(II) atoms are coordinated in a bidentate fashion by the phenolate O and imine N atoms of the Schiff base ligand. Two Cl(-) anions complete the tetra-hedral coordination in each case. The most obvious difference between the two forms is that the Zn-L (L = O, N, Cl) bond lengths in both unique mol-ecules are longer than those found in the monoclinic polymorph, or indeed in other similar complexes. In the crystal, mol-ecules are linked through N-H⋯O and N-H⋯Cl hydrogen bonds, forming chains along the b axis.
