The crystal structure of a new fluorinated dithiocarbazate imine containing the isatin moiety, 4-fluorobenzyl (Z)-2-(2-oxoindolin-3-ylidene)hydrazine-1-carbodithioate, is described.
The title compound, C16H12FN3OS, a fluorinated dithiocarbazate imine derivative, was synthesized by the one-pot, multi-component condensation reaction of hydrazine hydrate, carbon disulfide, 4-fluorobenzyl chloride and isatin. The compound demonstrates near-planarity across much of the molecule in the solid state and a Z configuration for the azomethine C=N bond. The Z form is further stabilized by the presence of an intramolecular N—H⋯O hydrogen bond.

The bis-chelated mononuclear nickel(II) complex shows inversion symmetry, with the dithiocarbazato ligand in the usual trans configuration and the central metal cation in a square-planar coordination environment.
The central NiII atom in the title complex, [Ni(C13H25N2S2)2], is located on an inversion center and adopts a roughly square-planar coordination environment defined by two chelating N,S donor sets of two symmetry-related ligands in a trans configuration. The Ni—N and Ni—S bond lenghts are 1.9193 (14) and 2.1788 (5) Å, respectively, with a chelating N—Ni—S bond angle of 86.05 (4)°. These data are compared with those measured for similar dithiocarbazato ligands that bear n-octyl or n-hexyl alkyl chains. Slight differences are observed with respect to the phenylethylidene derivative where the ligands are bound cis relative to one another.
The structure of the title compound, [Ag2(NO3)2(C14H18N2)2] n , contains subtle differences in ligand, metal, and counter-anion coordination. One quinoxaline ligand uses one of its quinoxaline N atoms to bond to one silver cation. That silver cation is bound to a second quinoxaline which, in turn, is bound to a second silver atom, thereby using both of its quinoxaline N atoms. A nitrate group bonds with one of its O atoms to the first silver and uses the same oxygen to bond to a silver atom (related by symmetry to the second), thereby forming an extended network. The second nitrate group on the other silver bonds via two nitrate O atoms; one silver cation therefore has a coordination number of three whereas the second has a coordination number of four.

The coordination geometry of the pentacoordinated SiIV atom in the title complex is a distorted trigonal bipyramid.
The title SiIV complex, C16H21NO3Si, is built up by a tridentate dinegative Schiff base ligand bound to a silacyclohexane unit. The coordination geometry of the pentacoordinated SiIV atom is a distorted trigonal bipyramid. The presence of the silacyclohexane ring in the complex leads to an unusual coordination geometry of the SiIV atom with the N atom from the Schiff base ligand and an alkyl-C atom in apical positions of the trigonal bipyramid. There is a disorder of the methyl group at the imine bond with two orientations resolved for the H atoms [major orientation = 0.55 (3)]. In the crystal, C—H⋯O interactions are found within corrugated layers of molecules parallel to the ab plane.
