Crystal structure of bis-(aceto-phenone 4-benzoyl-thio-semicarbazonato-κ(2) N (1),S)nickel(II).

In the asymmetric unit of the title complex, [Ni(C16H14N3OS)2], the nickel ion is tetra-coordinated in a distorted square-planar geometry by two independent mol-ecules of the ligand which act as mononegative bidentate N,S-donors and form two five-membered chelate rings. The ligands are in trans (E) conformations with respect to the C=N bonds. The close approach of hydrogen atoms to the Ni(2+) atom suggests anagostic inter-actions (Ni⋯H-C) are present.

High activity of Ag-doped Cd0.1Zn0.9S photocatalyst prepared by the hydrothermal method for hydrogen production under visible-light irradiation.

Background: The hydrothermal method was used as a new approach to prepare a series of Ag-doped Cd0.1Zn0.9S photocatalysts.

Bromido({2-[2-(diphenyl-phosphan-yl)benzyl-idene]hydrazin-1-yl-idene}(4-meth-oxy-anilino)methane-thiol-ato)palladium(II) acetone monosolvate.

In the title compound, [PdBr(C(27)H(23)N(3)OPS)]·C(3)H(6)O, the coordination geometry about the Pd(II) atom is distorted square-planar, arising from the attached Br, S, P and N atoms (N and Br are trans), the maximum deviation from the plane being 0.2053 (4) Å for the N atom. The three benzene rings attached to the P atom make dihedral angles of 69.

{5,5'-Dimeth-oxy-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methanylyl-idene)]diphenolato}palladium(II).

In the title compound, [Pd(C(21)H(24)N(2)O(4))], the complete mol-ecule is generated by crystallographic mirror symmetry with the Pd and three C atoms lying on the mirror plane. The Pd-O and Pd-N distances are 1.9932 (6) and 2.

Dichlorido{4-cyclo-hexyl-1-[1-(2-pyridyl-κN)ethyl-idene]thio-semicarbazidato-κN,S}methyl-tin(IV).

The monodeprotonated Schiff base ligand in the title compound, [Sn(CH(3))(C(14)H(19)N(4)S)Cl(2)], N,N',S-chelates to the Sn atom, which is six-coordinated in an octa-hedral environment. The three coordinating atoms along with the methyl C atom comprise a square plane, above and below which are positioned the Cl atoms. The amino group is a hydrogen-bond donor to a Cl atom of an adjacent mol-ecule, the hydrogen bond giving rise to a helical chain extending parallel to [100].

{2,2'-[(2,2-Dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]diphenolato}palladium(II) ethanol hemisolvate.

The asymmetric unit of the title complex, [Pd(C(19)H(20)N(2)O(2))]·0.5C(2)H(5)OH, contains two mol-ecules of a Pd(II) complex of a Schiff base ligand with an N(2)O(2) donor set and one ethanol mol-ecule. The Pd(II) centers are in distorted square-planar geometries with the N(2)O(2) donor atoms of the tetra-dentate Schiff base dianions.
