Synthesis, crystal structure and Hirshfeld surface analysis of (2,2')-2,2'-(3-meth-oxy-3-phenylpropane-1,2-diyl-idene)bis-(hydrazine-1-carbo-thioamide) di-methyl-formamide monosolvate.

The overall mol-ecular configuration of the title compound, CHNOS·CHNO, is stabilized in the solid state by intra-molecular C-H⋯N, C-H⋯O, N-H⋯N and N-H⋯O inter-actions, forming (5) ring motifs. In the crystal, mol-ecules are linked to each other and solvent di-methyl-formamide mol-ecules by N-H⋯S, N-H⋯O, C-H⋯O and C-H⋯S hydrogen bonds, forming a three dimensional network. The phenyl ring of the title compound is disordered over two sites with an occupancy ratio of 0.

Crystal structure and Hirshfeld surface analysis of 2-(4-chloro-phen-yl)-4-(di-meth-oxy-meth-yl)-5-phenyl-1,3-thia-zole.

In the title compound, CHClNOS, the thia-zole ring subtends dihedral angles of 13.12 (14) and 43.79 (14) ° with the attached chloro-phenyl and phenyl rings, respectively.

Pd-Fe nanoparticles stabilized by chitosan derivatives for perchloroethene dechlorination.

A series of chitosan-stabilized Pd-NZVI (nano-zero-valent-iron) catalysts for dechlorination with variation in their composition and in the nature of the polymer has been prepared. The synthesis procedures and palladium and chitosan contents were optimized. It was demonstrated by the XPS method that Fe and Pd in Fe-Pd/chitosan samples exist in the metallic state.
