[2-(1-{2-[Aza-nid-yl(ethyl-sulfan-yl)methyl-idene-?N]hydrazin-1-yl-idene-?N¹}eth-yl)phenolato-?O](pyridine-?N)nickel(II).

ABSTRACT: 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.

[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).

Project description: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.

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)%.

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.

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.

The dihedral angle between the two aromatic rings is 6.33?(5)°. In the crystal, pairs of centrosymmetrically related mol-ecules are linked through N-H?N hydrogen bonds, forming N-H?N dimers with graph-set motif R(2) (2)(8).

(6-Hydroxy-2-{[2-(N-methyl-carbamo-thiol-yl)hydrazin-1-yl-idene-?N,S]meth-yl}-phenolato-?O)(triphenyl-phosphane-?P)nickel(II) chloride.

Project description:The deprotonated Schiff base ligand in the title salt, [Ni(C(9)H(10)N(3)O(2)S)(C(18)H(15)P)]Cl, functions as an N,O,S-chelating anion to the phosphine-coordinated nickel(II) atom, which exists in a distorted square-planar geometry. The hy-droxy group forms an intra-molecular O-H?O hydrogen bond. The two amino groups of the cation are hydrogen-bond donors to the chloride anion; the hydrogen bonds generate a chain structure running along the b axis.

Bis[2-(1-imino-eth-yl)phenolato-?N,O]nickel(II).

Project description:There are one and a half independent mol-ecules in the asymmetric unit of the title compound, [Ni(C(8)H(8)NO)(2)], one of which is situated on an inversion center. In both mol-ecules, the Ni(II) ion is coordinated by two O and two N atoms from two Schiff base ligands in an approximate square-planar geometry. Inter-molecular N-H?O hydrogen bonds link three mol-ecules into centrosymmetric trimer. The crystal packing exhibits weak inter-molecular C-H?O hydrogen bonds and voids of 37?Å(3).

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.

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 π-π inter-actions [ring centroid-centroid distance = 3.5739 (19) Å] into double layers.

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].
