Crystal structure of S-hexyl (E)-3-(4-methylbenzylidene)dithiocarbazate
In the title compound, C15H22N2S2, the di-thio-carbazate group adopts an E conformation with respect to the C=N bond of the benzyl-idene moiety. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked via C-H⋯π inter-actions, forming chains propagating along [100].

The whole mol-ecule of the title complex, [Pd(C15H21N2S2)2], is generated by twofold rotational symmetry. The palladium(II) atom exhibits a square-planar coordination geometry, and is located on the crystallographic twofold axis that induces a cis configuration of the N,S chelating ligands. In the crystal, mol-ecules stack along the c-axis direction and there are no significant inter-molecular ...
متن کاملCrystal structure of bis[S-hexyl 3-(4-methylbenzylidene)dithiocarbazato-κ2 N 3,S]nickel(II)
In the title complex, [Ni(C15H21N2S2)2], the Ni(II) atom exhibits a square-planar coordination geometry and is located on an inversion centre leading to a trans configuration of the N,S-chelating ligands. In the crystal, the complex mol-ecules stack at a distance of 4.6738 (3) Å along the a axis, which exclude any significant inter-actions between the aromatic rings.

In the title compound, C18H17N3O3, the dihedral angle between the planes of the indazole ring system [maximum deviation = 0.012 (1) Å] and the pyran-2,4-dione ring is 54.03 (6)°. An intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. The same H atom also participates in an inter-molecular N-H⋯O hydrogen bond, which generates an inversion dimer. The dimers are linked by weak C-H⋯O contacts,...
