Bis{2-[(5-hy-droxy-pent-yl)imino-meth-yl]phenolato-?(2) N,O (1)}copper(II).

ABSTRACT: In the title compound, [Cu(C12H16NO2)2], the Cu(II) ion, located on a center of inversion, is coordinated by two singly deprotonated Schiff base ligands derived from condensation of salicyldehyde and 1-amino-pentan-5-ol. The imino N and phenol O atoms from both ligands offer a square-planar arrangement around the metal ion. The Cu-N and Cu-O bond lengths are 2.0146?(15) and 1.8870?(12)?Å, respectively. Since the Cu-O and Cu-N bond lengths are different, it can be concluded that the resulting geometry of the complex is distorted. The aliphatic -OH group of the ligand is not coordinated and points away from the metal coordination zone and actively participates in hydrogen bonding connecting two other units and thus stabilizing the crystal lattice. This results in a two-dimensional extended array parallel to (201).

Bis(2-hy-droxy-imino-methyl-6-meth-oxy-phenolato-κ(2)N,O(1))copper(II).

Project description:In the title compound, [Cu(C(8)H(8)NO(3))(2)], the nearly planar mol-ecule (r.m.s. deviation = 0.037 Å) is centrosymmetric with the Cu(II) atom lying on an inversion center. The Cu(II) atom is tetra-coordinated, displaying a slightly distorted square-planar geometry. The main deviation from the ideal geometry is seen in the differences in the Cu-O [1.8833 (10) Å] and Cu-N [1.9405 (13) Å] bond lengths, while angular deviations are less than 3°. Intra-molecular O-H⋯O and inter-molecular Csp(2)-H⋯O hydrogen bonds form S(5) and R(2) (2)(8) ring motifs, respectively. The latter inter-action results in chains of mol-ecules along [100].

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 title mononuclear nickel complex, [Ni(C(9)H(9)BrNO(2))(2)]·H(2)O, was obtained by the reaction of 5-bromo-salicyl-aldehyde, 2-amino-ethanol and nickel nitrate in methanol. The Ni(II) atom is six-coordinated by two phenolate O, two imine N and two hy-droxy O atoms from two crystallographically different Schiff base ligands, forming an octa-hedral geometry. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O and O-H⋯Br hydrogen bonds, forming a three-dimensional network.

Bis{?-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}bis-({2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}copper(II)).

Project description:The title compound, [Cu2(C9H10NO2)4], is built of discrete centrosymmetric dimers. The Cu(II) atoms are each five coordinated by two deprotonated Schiff base ligands that are bonded differently to the metal atoms. Of the two phenolate O atoms, one is coordinated to one Cu(II) atom, whereas another bridges the two metal atoms. The basal plane of the square pyramid around Cu(II) atoms is formed by the imino N and phenolate O atoms of the bidentate and the monodentate/bidentate Schiff base ligands. The bridging phenolate oxygen occupies the apical position of the coordination sphere with a considerably longer Cu-O bond length. In the crystal, the dimeric mol-ecules pack relative to each other in such a way that the Cu2O2 planes of adjacent dimers are orthogonal.

Project description:In the title thio-cyanate-bridged polynuclear copper(II) complex, [Cu(C(10)H(12)NO(3))(NCS)](n), the Cu atom is five-coordinated in a square-pyramidal geometry, with one phenolato O, one imino N and one hy-droxy O atom of a Schiff base ligand and one thio-cyanato N atom defining the basal plane, and with one thio-cyanato S atom occupying the apical position. In the crystal structure, pairs of adjacent complex mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds into dimers. The dimers are further linked via Cu⋯S inter-actions, forming two-dimensional layers parallel to the bc plane.

Bis{?-2-[(pyridin-2-yl)imino-meth-yl]phenolato}bis-[(2-formyl-phenolato)copper(II)].

Project description:The asymmetric unit of the title compound, [Cu(2)(C(12)H(9)N(2)O)(2)(C(7)H(5)O(2))(2)], contains two independent (2-formyl-phen-olato){2-[(pyridin-2-yl)imino-meth-yl]phenolato}copper(II) mol-ecules that form pseudocentrosymmetric dimers via inter-actions between the Cu and pyridyl N atoms of independent monomers. The square-planar geometry of the Cu atoms in the monomer thus becomes square-based pyramidal in the dimer. The crystal studied was an inversion twin, with unequal populations of 0.353?(17) and 0.647?(17).

Crystal structure of bis-(2-{[1,1-bis-(hy-droxy-meth-yl)-2-oxidoeth-yl]imino-meth-yl}-6-meth-oxy-phenolato)manganese(IV) 0.39-hydrate.

Project description:The title compound, [Mn(C12H15NO5)2]·0.39H2O, is a 0.39 hydrate of the isostructural complex bis-(2-{[1,1-bis-(hy-droxy-meth-yl)-2-oxidoeth-yl]imino-meth-yl}-6-meth-oxy-phenolato)manganese(IV) that has previously been reported by Back, Oliveira, Canabarro & Iglesias [Z. Anorg. Allg. Chem. (2015), 641, 941-947], based on room-temperature data. The current structure that was determined at 100 K reveals a lengthening of the c cell parameter compared with the published one due to the incorporation of the partial occupancy water mol-ecule. The title compound crystallizes in the tetra-gonal chiral space group P41212; the neutral [Mn(IV)(C12H15NO5)2] mol-ecule is situated on a crystallographic C 2 axis. The overall geometry about the central manganese ion is octa-hedral with an N2O4 core; each ligand acts as a meridional ONO donor. The coordination environment of Mn(IV) at 100 K displays a difference in one of the two Mn-O bond lengths, compared with the room-temperature structure. In the crystal, the neutral mol-ecules are stacked in a helical fashion along the c-axis direction.

Crystal structure of tetra-kis-(?3-2-{[1,1-bis-(hy-droxy-meth-yl)-2-oxidoeth-yl]imino-meth-yl}phenolato)tetra-copper(II) ethanol monosolvate 2.5-hydrate.

Project description:The title compound, [Cu4(C11H13NO4)4]·CH3CH2OH·2.5H2O, is an electronically neutral tetra-nuclear copper(II) complex with a cubane-like Cu4O4 core. The complete molecule has point group symmetry 2. The phenol hy-droxy group and one of the three alcohol hy-droxy groups of each 2-{[tris-(hy-droxy-meth-yl)meth-yl]imino-meth-yl}phenol ligand are depro-ton-ated, while the secondary amine and the other two hy-droxy groups remain unchanged. The Cu(II) atoms in the Cu4O4 core are connected by four ?3-O atoms from the deprotonated alcohol hy-droxy groups. Each of the penta-coordinated Cu(II) ions has an NO4 distorted square-pyramidal environment through coordination to the tridentate Schiff base ligands. The Cu-N/O bond lengths span the range 1.902?(4)-1.955?(4)?Å, similar to values reported for related structures. There are O-H?O hydrogen-bond inter-actions between the complex molecules and the ethanol and water solvent molecules, leading to the formation of a three-dimensional network. The ethanol solvent molecule is disordered about a twofold rotation axis. One of the two independent water molecules is also located on this twofold rotation axis and shows half-occupancy.
