Oxido[2-{(E)-[((1E)-{(E)-2-[1-(2-oxido-phen-yl)ethyl-idene]hydrazin-1-yl-idene}(prop-2-en-1-ylsulfan-yl)meth-yl)-imino]-meth-yl}phenolato]vanadium(IV).

ABSTRACT: The V(IV) atom in the title complex, [V(C(19)H(17)N(3)O(2)S)O], is coordinated by two N and two O atoms of the dianionic tetra-dentate Schiff base ligand and the terminal oxide O atom. The N(2)O(3) donor set defines a square-pyramidal coordination geometry with the oxide O atom in the apical site. Some buckling in the tetra-dentate ligand is indicated by the dihedral angle of 17.92?(19)° between the six-membered chelate rings. Supra-molecular chains are formed along the b axis via C-H?O contacts in the crystal. The chains are connected into a layer in the ab plane via C-H?? inter-actions. The atoms comprising the -SCH(2)-CH=CH(2) and methyl substituents were found to be disordered in a 0.916?(2):0.088?(2) ratio. The crystal studied was found to be twinned by nonmerohedry with a 28.1?(4)% minor twin component.

Project description:In the title mononuclear dioxidovanadium(V) complex, [V(C(13)H(16)BrN(2)O(2))O(2)], the V(V) atom is five-coordinated by one phenolate O, one imine N and one morpholine N atom of the Schiff base ligand, and by two oxide O atoms, forming a distorted square-pyramidal geometry.

n-Butyl-dichlorido(2-{(1E)-1-[2-(pyridin-2-yl)hydrazin-1-yl-idene]eth-yl}phenolato)tin(IV).

Project description:Two independent mol-ecules comprise the asymmetric unit of the title compound, [Sn(C(4)H(9))(C(13)H(12)N(3)O)Cl(2)]. The Sn atom in each is coordinated by the tridentate ligand via the phenoxide O, hydrazine N and pyridyl N atoms, forming five- and six-membered chelate rings. The approximately octa-hedral coordination geometry is completed by the ?-C atom of the n-butyl group (which is trans to the hydrazine N atom) and two mutually trans Cl atoms. Differences between the mol-ecules are evident in the relative planarity of the chelate rings and in the conformations of the n-butyl groups [C-C-C-C = 177.2?(5) and -64.4?(11)°]. Significant differences in the Sn-Cl bond lengths are related to the formation of N-H?Cl hydrogen bonds, which link the mol-ecules comprising the asymmetric unit into dimeric aggregates. These are consolidated in the crystal packing by C-H?Cl contacts. The structure was refined as an inversion twin; the minor twin component is 37?(3)%.

(E)-1-Phenyl-2-({5-[(1E)-(2-phenyl-hydrazin-1-yl-idene)meth-yl]-2-thien-yl}methyl-idene)hydrazine.

Project description:The title mol-ecule, C(18)H(16)N(4)S, adopts a U-shape with the aromatic groups lying syn and orientated in the same direction as the thio-phene S atom. The conformation about each of the C=N bonds is E. Overall, the mol-ecule is curved as seen in the dihedral angle of 30.26?(19)° formed between the terminal benzene rings. In the crystal, supra-molecular chains along the c axis are formed by a combination of N-H?N hydrogen bonds and N-H?? inter-actions.

Benzoic acid-4-{(1E)-[(E)-2-(pyridin-4-yl-methyl-idene)hydrazin-1-yl-idene]meth-yl}pyridine (2/1).

Project description:In the title co-crystal, C(12)H(10)N(4)·2C(7)H(6)O(2), the complete 4-pyridine-aldazine mol-ecule is generated by a crystallographic centre of inversion. In the crystal, mol-ecules are connected into a three component aggregate via O-H?N hydrogen bonds. As both the benzoic acid [O-C-C-C torsion angle = 174.8?(2)°] and 4-pyridine-aldazine (r.m.s. deviation of the 16 non-H atoms = 0.041?Å) mol-ecules are almost planar, the resulting three-component aggregate is essentially planar. The crystal packing comprises layers of the three-component aggregates of alternating orientation stacked along the b axis; the connections between the mol-ecules are of the types C-H?? and ?-? [pyridine-benzene centroid-centroid distance = 3.787?(4)?Å].

Chlorido{?-2,6-bis-[(2-amino-eth-yl)imino-meth-yl]-4-chloro-phenolato}-?-oxido-dicopper(II) trihydrate.

Project description:In the title dinuclear complex, [Cu(2)(C(14)H(20)ClN(4)O)ClO]·3H(2)O, one Cu(II) cation assumes a distorted square-planar coordination geometry and the other a distorted square-pyramidal coordination geometry. Both Cu(II) cations are N,N',O-chelated by one arm of the 2,6-bis-[(2-amino-eth-yl)imino-meth-yl]-4-chloro-phenolate anion, and one oxide anion bridges the two Cu(II) cations, forming a dinuclear complex. One of the Cu(II) cations is further coordinated by an Cl(-) anion in the apical direction. In the crystal, lattice water mol-ecules are linked with the complex mol-ecule via O-H?Cl hydrogen bonds while O-H?O hydrogen bonding occurs between lattice water mol-ecules , forming three-dimensional network structure.

Crystal structure of (2-formyl-phenolato-?(2) O,O')oxido(2-{[(2-oxidoeth-yl)imino]-meth-yl}phenolato-?(3) O,N,O')vanadium(V).

Project description:In the unsymmetrical title vanadyl complex, [V(C9H9NO2)(C7H5O2)O], one of the ligands (2-formyl-phenol) is disordered over two sets of sites, with an occupancy ratio of 0.55?(2):0.45?(2). The metal atom is hexa-coordinated, with a distorted octa-hedral geometry. The vanadyl O atom (which subtends the shortest V-O bond) occupies one of the apical positions and the remaining axial bond (the longest in the polyhedron) is provided by the (disordered) formyl O atoms. The basal plane is defined by the two phenoxide O atoms, the imino-alcoholic O and the imino N atom. The planes of the two benzene rings are almost perpendicular to each other, subtending an inter-planar angle of 84.1?(2)° between the major parts. The crystal structure features weak C-H?O and C-H?? inter-actions, forming a lateral arrangement of adjacent molecules.

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.

2-[(1E)-[(Z)-2-({[(1Z)-[(E)-2-[(2-Hy-droxy-phen-yl)methyl-idene]hydrazin-1-yl-idene]({[(4-methyl-phen-yl)meth-yl]sulfan-yl})meth-yl]disulfan-yl}({[(4-methyl-phen-yl)meth-yl]sulfan-yl})methyl-idene)hydrazin-1-yl-idene]meth-yl]phenol: crystal structure, Hirshfeld surface analysis and computational study.

Project description:The complete mol-ecule of the title hydrazine carbodi-thio-ate derivative, C32H30N4O2S4, is generated by a crystallographic twofold axis that bis-ects the di-sulfide bond. The mol-ecule is twisted about this bond with the C-S-S-C torsion angle of 90.70?(8)° indicating an orthogonal relationship between the symmetry-related halves of the mol-ecule. The conformation about the imine bond [1.282?(2)?Å] is E and there is limited delocalization of ?-electron density over the CN2C residue as there is a twist about the N-N bond [C-N-N-C torsion angle = -166.57?(15)°]. An intra-molecular hydroxyl-O-H?N(imine) hydrogen bond closes an S(6) loop. In the crystal, methyl-ene-C-H??(tol-yl) contacts assemble mol-ecules into a supra-molecular layer propagating in the ab plane: the layers stack without directional inter-actions between them. The analysis of the calculated Hirshfeld surfaces confirm the importance of H?H contacts, which contribute 46.7% of all contacts followed by H?C/C?H contacts [25.5%] reflecting, in part, the C-H??(tol-yl) contacts. The calculation of the inter-action energies confirm the importance of the dispersion term and the influence of the stabilizing H?H contacts in the inter-layer region.
