ABSTRACT: The U(VI) cation in the title complex, [U(C(17)H(14)BrN(3)O(2)S)O(2)(C(4)H(10)O)], exists within a distorted penta-gonal-bipyramidal geometry, where the oxide atoms occupy the axial positions [O-U-O = 179.8?(3)°] 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 2-butanol mol-ecule. In the crystal, centrosymmetric aggregates are formed via pairs of hy-droxy-phenolate O-H?O hydrogen bonds. The azomethine C=N atoms, the ethyl-thiolyl group, the 2-butanol mol-ecule and Br atom are disordered over two positions in a 0.627?(3):0.373?(3) ratio.

Project description:In the title complex, [U(C17H14BrN3O2S)O2(C2H5OH)], the U(VI) cation has a distorted penta-gonal-bipyramidal environment with the penta-gonal plane defined by two N and two O atoms of the tetra-dentate Schiff base ligand and the O atom of the ethanol mol-ecule. Two oxide O atoms occupy the axial positions. The azomethine C=N group and the Br atom are disordered over two positions in a 0.8356?(18):0.1644?(18) ratio. The ethyl-thiolyl group is disordered over three conformations in a 0.8356?(18):0.085?(6):0.079?(6) ratio, and the ethanol ligand is also disordered over three orientations in a 0.470?(16):0.277?(19):0.253?(18) ratio. In the crystal, mol-ecules form centrosymmetric dimers through hydrogen bonding between ethanol O-H donors and phenolate O-atom acceptors. Weak C-H?O inter-actions consolidate the crystal packing.

(E)-1-[2-(Methyl-sulfan-yl)phen-yl]-2-({(E)-2-[2-(methyl-sulfan-yl)phen-yl]hydrazinyl-idene}(nitro)-meth-yl)diazene.

Project description:In the title compound, C(15)H(15)N(5)O(2)S(2), the phenyl rings make dihedral angles of 4.03?(4) and 9.77?(5)° with the plane defined by the central N-N-C-N-N atoms (r.m.s. deviation = 0.010?Å). The C-S-C-C torsion angles of the methyl-sulfanyl groups with their respective phenyl rings are -7.47?(13) and -72.07?(13)°. The shortest centroid-centroid distance of 3.707?Å occurs between the two ?-systems N-N-C-N-N and the benzene ring in the diazene 1-position. The H atom bound to the N atom is involved in intra-molecular N-H?N and N-H?S contacts, while the nitro O atoms are involved in inter-molecular C-H?O contacts.

4-[(4-Methyl-phen-yl)sulfan-yl]butan-2-one.

Project description:In the title compound, C11H14OS, all non-H atoms are essentially coplanar, with a mean deviation of 0.023?Å. In the crystal, centrosymmetrically related mol-ecules are weakly connected into dimers by pairs of C-H?O inter-actions. The dimers are further linked along the a axis by weak C-H?? and C-H?S inter-actions.

Synthesis and crystal structure of (E)-2-({2-[aza-niumyl-idene(methyl-sulfan-yl)meth-yl]hydrazinyl-idene}meth-yl)benzene-1,4-diol hydrogen sulfate.

Project description:The title mol-ecular salt, C9H12N3O2S+·HSO4 -, was obtained through the protonation of the azomethine N atom in a sulfuric acid medium. The crystal com-prises two entities, a thio-semicarbazide cation and a hydrogen sulfate anion. The cation is essentially planar and is further stabilized by a strong intra-molecular O-H?N hydrogen bond. In the crystal, a three-dimensional network is established through O-H?O and N-H?O hydrogen bonds. A weak intermolecular C-H?O hydrogen bond is also observed. The hydrogen sulfate anion exhibits disorder over two sets of sites and was modelled with refined occupancies of 0.501?(6) and 0.499?(6).

[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).

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.

Bis{?-2-[(2-oxidobenzyl-idene)amino-meth-yl]phenolato-?O,N,O'}bis-[(pyridine-?N)zinc(II)].

Project description:In the title centrosymmetric zinc(II) complex, [Zn(2)(C(4)H(13)NO(2))(2)(C(6)H(5)N)(2)], each Zn(II) atom is coordinated by two 2-[(2-oxidobenzyl-idene)amino-meth-yl]phenolate (L) ligands and one pyridine (py) mol-ecule in a distorted trigonal-bipyramidal geometry. Each L ligand behaves as a tridentate ligand and provides a phenolate oxygen bridge which links the two Zn(II) atoms. The ZnL(py) units are linked by ?-? inter-actions between adjacent pyridine mol-ecules, with a centroid-centroid distance of 3.724?Å, resulting in a two-dimensional structure.

[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.

Project description:In the centrosymmetric dinuclear title compound, [Dy(2)(C(15)H(12)N(3)O(2)S)(2)(NO(3))(4)]·2CH(3)OH, the two Dy(III) atoms are coordinated by two deprotonated 2-{[2-(1,3-benzothia-zol-2-yl)hydrazinyl-idene]meth-yl}-6-meth-oxy-phenol ligands and four nitrate ions, all of which are chelating. The crystal packing is stabilized by inter-molecular N-H?O hydrogen bonds and weak O-H?O inter-actions, forming a two-dimensional network parallel to (010).
