Six organotin(IV) complexes of pyruvic acid thiosemicarbazone ligand [H2PAT, (1)] with general formula [RSnCln-1 PAT)] [R = Me2, n = 1 (2); R = Bu2, n = 1 (3); R = Ph2, n = 1 (4); R = Me, n = 2 (5); R = Bu, n = 2 (6); R = Ph, n = 2 (7)] were synthesized by direct reaction of thiosemicarbazone ligand (1), base and organotin(IV) chloride(s) in absolute(More)
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(More)
BACKGROUND The hydrothermal method was used as a new approach to prepare a series of Ag-doped Cd0.1Zn0.9S photocatalysts. The effect of Ag doping on the properties and photocatalytic activity of Cd0.1Zn0.9S was studied for the hydrogen production from water reduction under visible light irradiation. RESULTS Compared to the series prepared by the(More)
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(More)
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 2.0029 (7) Å, respectively. The dihedral angle between two benzene rings of the ligand is 79.21 (4)°. In the crystal, C-H⋯O hydrogen(More)
Titanium dioxide (TiO2) is well-known as an active photocatalyst for degradation of various organic pollutants. Over the years, a wide range of TiO2 nanoparticles with different phase compositions, crystallinities, and surface areas have been developed. Due to the different methods and conditions used to synthesize these commercial TiO2 nanoparticles, the(More)
Palladium is arguably the most versatile and most widely applied catalytic metal in the field of fine chemicals due to its high selectivity and activity. Palladium catalyst offers an abundance of possibilities of carbon-carbon bond formation in organic synthesis. In this research, three different Schiff base ligands have been prepared by condensation(More)
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. The ethanol mol-ecule(More)
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 69.78 (7),(More)
