{2-[1-(2-Meth-oxy-6-oxidophenyl-κO (6))ethyl-idene]-N-methyl-hydrazinecarbo-thio-amidato-κ(2) N (2),S}(tri-phenyl-phosphane-κP)palladium(II) ethanol monosolvate.

In the title compound, [Pd(C11H13N3O2S)(C18H15P)]·C2H5OH, the Pd(II) atom is tetra-coordinated in a slightly distorted square-planar environment by three donor atoms (NOS) from a thio-semicarbazonate ligand, forming five- and six-membered chelate rings, and a P atom from a neutral tri-phenyl-phosphane group. The five-membered ring adopts a distorted envelope conformation with Pd(II) as the flap atom, while the six-membered ring forms a slightly twisted screw-boat conformation. A slightly distorted screw-boat form of a meth-oxy-phenyl group is fused to the six-membered ring. Weak C-H⋯O inter-actions form dimers in the asymmetric unit and along [001] which help to stabilize the crystal packing.

2-[1-(2-Hy-droxy-6-meth-oxy-phen-yl)ethyl-idene]-N-methyl-hydrazinecarbothio-amide acetonitrile monosolvate.

In the title compound, C11H15N3O2S·C2H3N, the dihedral angle between the benzene ring and the mean plane of the hydrazinecarbothio-amide group is 75.1 (2)°. In the crystal, the main mol-ecule is linked to the solvent mol-ecule by a weak N-H⋯N hydrogen bond while O-H⋯S hydrogen bonds link the mol-ecules into columns along [100].
