In the title polymeric coordination compound, [Sn(C6H5)3(C9H8N3O3)]n, the SnIV atom is in a distorted trigonal-bipyramidal geometry, being coordinated by two O atoms from two 2-(2-picolinoylhydrazono)propanoate ligands and three phenyl groups. Adjacent Sn atoms are bridged by the 2-(2-picolinoylhydrazono)propanoate ligand through one carbonyl O atom and one carboxylate O atom, forming a chain structure propagating parallel to [100]. An intramolecular N—H⋯O hydrogen bond is observed.

The reaction was carried out under nitrogen atmosphere. 2-(2-Picolinoylhydrazono)propanoic acid (1 mmol) and sodium ethoxide (1.2 mmol) were added to a solution of benzene (30 ml) in a Schlenk flask and stirred for 0.5 h. Triphenyltin chloride (1 mmol) was then added to the reactor and the reaction mixture was stirred for 4 h at 313 K. The resulting clear solution was evaporated under vacuum. The product was crystallized from a mixture of dichloromethane/methanol (v/v 1:1) to yield colorless block crystals of the title compound (yield 78%).
H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 (aromatic) and 0.96 (methyl) Å, and N—H = 0.86 Å and with Uiso(H) = 1.2(1.5 for methyl)Ueq(C,N).
Recently, we have reported some organotin(IV) complexes with pyruvic acid isonicotinyl hydrazone (Yin et al., 2005). As a part of our ongoing investigations in this field, we have synthesized the title compound and present its
here.The title compound (Fig. 1) forms an extended one-dimensional chain structure arising from Sn—O bridges formed by the 2-(2-picolinoylhydrazono)propanoate ligand. The SnIV atom assumes a distorted trigonal-bipyramidal coordination geometry, with atoms O3 and O2i in the axial positions [O3—Sn1—O2i = 175.65 (13)°, symmetry code: (i) x+1, y, z] and the atoms C10, C16 and C22 in the equatorial positions. One of the two Sn—O bond lengths is shorter and the other is longer (Table 1). The complex involves an intramolecular N—H···O hydrogen bond (Table 2).

Recently, we have reported some organotin(IV) complexes with pyruvic acid isonicotinyl hydrazone (Yin et al., 2005). As a part of our ongoing investigations in this field, we have synthesized the title compound and present its crystal structure here.
The title compound (Fig. 1) forms an extended one-dimensional chain structure arising from Sn—O bridges formed by the 2-(2-picolinoylhydrazono)propanoate ligand. The SnIV atom assumes a distorted trigonal-bipyramidal coordination geometry, with atoms O3 and O2i in the axial positions [O3—Sn1—O2i = 175.65 (13)°, symmetry code: (i) x+1, y, z] and the atoms C10, C16 and C22 in the equatorial positions. One of the two Sn—O bond lengths is shorter and the other is longer (Table 1). The complex involves an intramolecular N—H···O hydrogen bond (Table 2).
