Bis{benzyl 3-[(1H-indol-3-yl)methyl­idene]dithio­carbazato-κ2 N 3,S}palladium(II) N,N-dimethyl­formamide disolvate

In the title compound, [Pd(C17H14N3S2)2]·2C3H7NO, the deprotonated Schiff base ligand acts as an N,S-bidentate chelate, forming a five-membered ring with the metal atom. The PdII ion, located on an inversion center, is four-coordinated by two of the Schiff base ligands in a square-planar geometry. In the crystal, the indolic NH groups are bonded to the dimethyl­formamide (DMF) solvent mol­ecules via an N—H⋯O inter­action. In addition, C—H⋯S inter­actions are observed

Bis{benzyl N′-[(1H-indol-3-yl)methyl­ene]dithio­carbazato-κ2 N′,S}copper(II) N,N-dimethyl­formamide disolvate

In the structure of [Cu(C17H14N3S2)2]·2C3H7NO, the Cu atom (site symmetry ) is N,S-chelated by the two deprotonated Schiff-base anions that define a distorted square-planar geometry. An N—H⋯O hydrogen bond links the mononuclear complex to the DMF solvent mol­ecules

Bis{benzyl 3-[(1H-indol-3-yl)methyl­idene]dithio­carbazato-κ2 N 3,S}palladium(II) pyridine disolvate

The dihedral angle between the aromatic ring planes within the ligand is 71.12 (9)°. The indole NH groups are bonded to the pyridine solvent mol­ecules via an N—H⋯N inter­action. The crystal structure is consolidated by inter­molecular C—H⋯S inter­actions

3,4,5-Trihydr­oxy-N′-[(1-methyl-1H-indol-2-yl)methyl­idene]benzohydrazide

The structure of the title compound, C17H15N3O4, displays inter­molecular O—H⋯N and O—H⋯O hydrogen bonding between adjacent mol­ecules. Intra­molecular O—H⋯O hydrogen bonds also occur. The molecule is essentially planar with a deviation of 0.090 (1) Å from the best plane running through the connected ring systems

Benzyl N′-(1H-indol-2-ylmethyl­ene)hydrazinecarbodithio­ate ethanol hemisolvate

In the crystal of the title compound, C17H15N3S2·0.5C2H6O, the mol­ecules are linked by a pair of N—Haliphatic⋯S hydrogen bonds across a center of inversion, forming a dimer. The ethanol solvent mol­ecule, which is statistically disordered about a crystallographic twofold rotation axis, accepts an N—Haromatic⋯O hydrogen bond; the hydr­oxy group of the solvent mol­ecule is not engaged in hydrogen bonding

The N′-(1-methyl-1H-indol-3-ylmethyl­idene)hydrazine­carbo­dithio­ate portion of the title mol­ecule, C18H17N3S2, is nearly planar; this unit and the phenyl ring subtend an angle of 112.9 (2)° at the methyl­ene C atom

1,5-Bis(2-oxoindolin-3-yl­idene)thio­carbonohydrazide tetra­hydro­furan monosolvate

In the thio­carbonohydrazide mol­ecule of the title compound, C17H12N6O2S·C4H8O, the terminal indolin-2-one ring systems make a dihedral angle of 20.13 (6)° with each other. Two intra­molecular N—H⋯O hydrogen bonds are present, each of which generates an S(6) ring. In the crystal, N—H⋯O hydrogen bonds lead to a mol­ecular chain running along the b axis. The tetra­hydro­furan solvent mol­ecule is disordered over two orientations in a 0.561 (11):0.439 (11) ratio

N′-[(5-Chloro-1H-indol-3-yl)methyl­ene]-3,4,5-trihydroxy­benzohydrazide
