[2-(1-{2-[Aza-nid-yl(ethyl-sulfan-yl)methyl-idene-?N]hydrazin-1-yl-idene-?N(1)}eth-yl)phenolato-?O](dimethyl sulfoxide-?O)dioxidomolybdenum(VI).

ABSTRACT: The Mo(VI) atom in the title complex, [Mo(C(11)H(13)N(3)OS)O(2)(C(2)H(6)OS)], is N,N',O-coordinated by the dianionic tridentate ligand, two mutually cis oxide O atoms and a dimethyl sulfoxide O atom, defining a distorted octa-hedral N(2)O(4) donor set. The most prominent feature of the crystal packing is the formation of inversion dimers via pairs of N-H?O hydrogen bonds and eight-membered {?HNMoO}(2) loops. The Schiff base ligand is disordered over two orientations of equal occupancy.

Project description:The Ni(II) atom in the title complex, [Ni(C??H??N?OS)(C?H?N)], exists within a square-planar N?O donor set provided by N,N',O atoms of the dianionic tridentate ligand and a pyridine N atom. The maximum deviation from the ideal geometry is seen in the N-Ni-N five-membered chelate bite angle of 83.28?(12)°. The pyridine mol-ecule forms a dihedral angle of 44.43?(6)° with the N?O donor set. Supra-molecular stacks along the a axis mediated by alternating ?-? inter-actions between the pyridine and five- [centroid-centroid distance = 3.4784?(16)?Å] and six-membered [3.4633?(17)?Å] chelate rings, feature in the crystal packing.

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)%.

tert-But-yl(2-hy-droxy-eth-yl)aza-nium 4-[(1,3-thia-zol-2-yl-aza-nid-yl)sulfon-yl]aniline.

Project description:Two pairs of independent cations and anions comprise the asymmetric unit of the title salt, C(6)H(16)NO(+)·C(9)H(8)N(3)O(2)S(2) (-). The cations are virtually superimposable and each exhibits a gauche disposition of the hy-droxy O and ammonium N atoms [the O-C-C-N torsion angles are 55.5?(3) and 57.5?(3)°]. Significant differences are seen in the mol-ecular structures of the anions as seen in the S-N-C-S [1.1?(3) and 32.9?(3)°] and C-S-N-C [-69.7?(2) and 91.4?(2)°] torsion angles. Despite the variations in conformation, intra-molecular hypervalent S?O inter-actions persist in each anion [3.078?(2) and 2.8730?(19)?Å]. In the crystal, supra-molecular double layers are formed in the bc plane, being sustained by O-H?N, N-H?O and N-H?N hydrogen bonding. These are connected along the a axis via C-H?O inter-actions.

Project description:The U(VI) atom in the title complex, [U(C(17)H(15)N(3)O(2)S)O(2)(C(2)H(6)OS)], exists within a distorted penta-gonal-pyramidal geometry where the oxide atoms occupy axial positions [O-U-O = 177.84?(14)°] and the penta-gonal plane is defined by the N(2)O(2) atoms of the tetra-dentate Schiff base ligand and the O atom of the dimethyl sulfoxide mol-ecule. In the crystal, centrosymmetric aggregates are formed via pairs of C-H?O inter-actions. The azomethine C=N atoms and ethyl-thiolyl group are disordered over two orientations in a 0.828?(3):0.172?(3) ratio.

Project description:The title Schiff base compound, C(33)H(30)N(4)O(4)·H(2)O, adopts an E configuration with respect to each C=N double bond. In the mol-ecule, there are naphthoxide anions and the protonated imino N atoms. Intra-molecular N-H⋯O hydrogen bonds lead to the formation of approximately planar (maximum deviation 0.029 Å for H atom) six-membered rings.. In the crystal, mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds as well as C-H⋯O contacts, leading to the formation of a three-dimensional network.

2-{(E)-1-[2-(4-Nitro-phen-yl)hydrazin-1-yl-idene]eth-yl}benzene-1,3-diol.

Project description:The title compound, C(14)H(13)N(3)O(4), is close to planar, the dihedral angle between the terminal benzene rings being 5.80?(16)°; the nitro group is coplanar with the benzene ring to which it is bonded [O-N-C-C torsion angle = -177.3?(3)°]. The hy-droxy group forms an intra-molecular hydrogen bond with the imine N atom, and the conformation about the imine bond is E. In the crystal, layers in the (101) plane with an undulating topology are formed by O-H?O and N-H?O hydrogen bonds along with C-H?O inter-actions. Centrosymmetrically related layers are connected via ?-? inter-actions [ring centroid-centroid distance = 3.5739?(19)?Å] into double layers.

Crystal structure of 1,2-bis-((benzyl-sulfan-yl){2-[1-(2-hy-droxy-phen-yl)ethyl-idene]hydrazin-1-yl-idene}meth-yl)disulfane.

Project description:The title compound, C32H30N4O2S4, consists of two Schiff base moieties, namely two S-benzyl-β-N-(2-hy-droxy-phenyl-ethyl-idene)di-thio-carbazate groups, which are connected through an S-S single bond. These two moieties are twisted with respect to each other, with a dihedral angle of 87.88 (4)° between the S2C=N planes. A bifurcated intra-molecular O-H⋯(N,S) hydrogen bond is observed in each moiety. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds into inversion dimers. The dimers are further stacked in a column along the b axis through weak C-H⋯π inter-actions.

Bis{(Z)-[(E)-2-(pyridin-2-yl-methyl-idene)hydrazin-1-yl-idene][(pyridin-2-yl)methyl-sulfan-yl]methane-thiol-ato}nickel(II).

Project description:The title compound, [Ni(C13H11N4S2)2], was obtained by the reaction of S-2-picolyldi-thio-carbazate and pyridine-2-carbaldehyde with nickel(II) acetate. The Ni(II) atom is located on a twofold rotation axis and is bonded to four N atoms at distances of 2.037 (8) and 2.109 (9) Å, and to two S atoms at a distance of 2.406 (3) Å, leading to a distorted octa-hedral coordination. The angle between the mean planes of the coordinating moieties of the two symmetry-related tridentate ligands is 83.3 (2)°. In the crystal, complex mol-ecules are linked by weak C-H⋯S hydrogen bonds, π-π inter-actions between the pyridine rings [centroid-centroid distance = 3.775 (9) Å] and C-H⋯π inter-actions. The hydrogen-bonding inter-actions lead to the formation of layers parallel to (010); π-π inter-actions link these layers into a three-dimensional network.

Bis{2-[(2-benzoyl-hydrazin-1-yl-idene)meth-yl]-6-meth-oxy-phenolato}iron(III) chloride monohydrate.

Project description:In the title mononuclear iron(III) complex, [Fe(C(15)H(13)N(2)O(3))(2)]Cl·H(2)O, the Fe(III) atom has a distorted octa-hedral geometry and is six-coordinated by four O atoms and two N atoms from two ligands. In the crystal structure, the complex cations, Cl(-) anions and water mol-ecules are connected into a chain along [100] through N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds. Two adjacent chains are linked by O-H⋯O hydrogen bonds.

Crystal structure of 2-((1E)-{2-[bis-(2-methyl-benzyl-sulfan-yl)methyl-idene]hydrazin-1-yl-idene}meth-yl)-6-meth-oxy-phenol.

Project description:In the title compound, C25H26N2O2S2, the central CN2S2 atoms are almost coplanar (r.m.s. deviation = 0.0058 Å). One phenyl ring clearly lies to one side of the central plane, while the other is oriented in the plane but splayed. Despite the different relative orientations, the phenyl rings form similar dihedral angles of 64.90 (3) and 70.06 (3)° with the central plane, and 63.28 (4)° with each other. The benzene ring is twisted with respect to the central plane, forming a dihedral angle of 13.17 (7)°. The S2C=N, N-N and N-N=C bond lengths of 1.2919 (19), 1.4037 (17) and 1.2892 (19) Å, respectively, suggest limited conjugation over these atoms; the configuration about the N-N=C bond is E. An intra-molecular O-H⋯N hydrogen bond is noted. In the crystal, phen-yl-meth-oxy C-H⋯O and phen-yl-phenyl C-H⋯π inter-actions lead to supra-molecular double chains parallel to the b axis. These are connected into a layer via meth-yl-phenyl C-H⋯π inter-actions, and layers stack along the a axis, being connected by weak π-π inter-actions between phenyl rings [inter-centroid distance = 3.9915 (9) Å] so that a three-dimensional architecture ensues.
