The metal atom of the title compound, [Zn(C13H8N3O2S)2]·C3H7NO·H2O, is O,N,O′-chelated by two deprotonated and it exists in a distorted octahedral geometry. The N–H groups of the ligands, the carbonyl group of the DMF molecule and uncoordinated water molecule engage in N—H⋯O and O—H⋯O interactions, generating a hydrogen-bonded ribbon that propagates along [110]. One thienyl ring is disordered over two positions in a 1:1 ratio.

The Schiff base was synthesized by condensing isatin and furoylhydrazine according to a literature procedure (Rodríguez-Argüelles et al., 2009). Zinc acetate (1 mmol) and the Schiff base (2 mmol) were heated in ethanol (100 ml) for 5 h; several drops of triethylamine were added. The solvent was removed and the product purified by recrystallization from DMF.
One thienyl ring is disordered over two positions. The disorder was modelled as follows: the C—C distances were restrained to 1.42 (1) Å and the C–S ones to 1.72 (1) Å. The displacement parameters of atoms S2 were paired with those of C16' (S2' with C16), and those of C14 with those of C15' (C14' with C15). The anisotropic displacement parameters were restrained to be nearly isotropic. The five atoms of each component ring were restrained to lie on a plane. As the disorder refined to a 1:1 ratio, the occupancy for each component was finally fixed as 0.50.
For the DMF molecule, the C—O distance was restrained to 1.25 (1) Å, the Ccarbonyl—N distance to 1.35 (1) Å and the Cmethyl—N distance to 1.45 (1) %A. The displacement parameters were also restrained to be nearly isotropic.
Carbon-bound H-atoms were placed in calculated positions (C–H = 0.93–0.96 Å) and were included in the
in the riding model approximation, with Uiso(H) set to 1.2 to 1.5Ueq(C). The amino and water H-atoms were located in a difference Fourier map, and were refined with a N–H/O–H distance restraint of 0.84 (1) Å; their Uiso parameters were freely refined. For the water molecule, the H···H distance was restrained to 1.37 (1) Å.Divalent cobalt, nickel, copper and zinc derivatives of Schiff base condensation product of isatin and 2-thienylcarboxylic acid hydrazide have been synthesized, and these are reported along with the
of the zinc derivative, which crystallizes with 1.75 molecules of methanol. The geometry is described as tetrahedral; however, if two weaker Zn···O interations are considered as bonding, the geometry is, in fact, octahedral (Rodríguez-Argüelles et al., 2009). The other compounds are expected to be chelated by the deprotonated Schiff base in a terdentate manner; for it to chelate, the anion has to rotate about the nitrogen-nitrogen bond. Such a rotation is observed in the present zinc complex, which crystallizes from DMF as a monohydrated monosolvate (Scheme I). The divalent metal atom is O,N,O'-chelated by two deprotonated Schiff base in an octahedral geometry (Fig. 1). The amino group, the carbonyl group of the DMF and the lattice water molecule engage in N–H···O and O–H···O hydrogen bonding interactions to generate a hydrogen-bonded ribbon that propagates along [110]. One thienyl ring is disordered over two positions in a 1:1 ratio.For the

Divalent cobalt, nickel, copper and zinc derivatives of Schiff base condensation product of isatin and 2-thienylcarboxylic acid hydrazide have been synthesized, and these are reported along with the crystal structure of the zinc derivative, which crystallizes with 1.75 molecules of methanol. The geometry is described as tetrahedral; however, if two weaker Zn···O interations are considered as bonding, the geometry is, in fact, octahedral (Rodríguez-Argüelles et al., 2009). The other compounds are expected to be chelated by the deprotonated Schiff base in a terdentate manner; for it to chelate, the anion has to rotate about the nitrogen-nitrogen bond. Such a rotation is observed in the present zinc complex, which crystallizes from DMF as a monohydrated monosolvate (Scheme I). The divalent metal atom is O,N,O'-chelated by two deprotonated Schiff base in an octahedral geometry (Fig. 1). The amino group, the carbonyl group of the DMF and the lattice water molecule engage in N–H···O and O–H···O hydrogen bonding interactions to generate a hydrogen-bonded ribbon that propagates along [110]. One thienyl ring is disordered over two positions in a 1:1 ratio.
