In the title one-dimensional coordination polymer, [Sn(CH3)3(C8H6NO4)]n, the SnIV atom is coordinated by three methyl C atoms and two carboxylate O atoms (one symmetry generated), resulting in an almost regular SnC3O2 trigonal pyramid. The C atoms occupy the equatorial sites and the O atoms occupy the axial sites. In the ligand, the dihedral angles between the benzene ring and the pendant acetate and nitro groups are 57.7 (1) and 36.9 (3)°, respectively. The bridging ligand leads to [010] chains in the crystal, with adjacent metal atoms related by a 21 screw axis. A weak π–π interaction exists between the centroids of symmetry-related benzene rings at a distance of 3.9131 (19) Å.
Keywords: crystal structure; one-dimensional coordination polymer; trimethyltin(IV) complex; π–π interaction.

The silver salt (1.44 g, 0.01 M) of 2-nitrophenyl acetic acid was suspended in 50 ml chloroform in a round bottom flask equipped with condenser and magnetic stirrer. Trimethyltin chloride (0.995 g, 0.01 M) in 5 ml of chloroform was added under inert atmosphere and reflux the reaction mixture for 4 h. The reaction mixture was allowed to cool to room temperature and stayed overnight then filtered. The residue was washed with chloroform and collected. It was concentrated on rotary evaporated and kept for crystallization. Colourless prisms were obtained after a week.
The H atoms were positioned geometrically (C—H = 0.93—0.97 Å) and refined as riding with Uiso(H) = xUeq(C), where x = 1.5 for methyl and x = 1.2 for other H-atoms.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

The tin complex (I), (Fig. 1) is in continuation of synthesizing various metal complexes with (2-nitrophenyl)acetic acid. In this context, we have reported the cobalt complex namely "Tetraaquabis((2-nitrophenyl)acetato-O) cobalt(II)" (Danish et al., 2015).
The crystal structures of catena-Poly[[trimethyltin(IV)]-µ-2-(2-chlorophenyl) acetato] (Wen et al., 2009), catena-[bis(µ2–3-(2- fluorophenyl)-2-methylprop-2-enoato)-hexamethyl-di-tin] (Tariq et al., 2013), catena-poly[[trimethyltin(IV)]-µ-2-(3-thienyl)acetato] (Yang et al., 2009), catena-((µ2–2-(3-benzoylphenyl)propanoato-)- trimethyl-tin(iv)) (Tahir et al., 1997a), {2-[(2,3-Dimethylphenyl)amino] benzoato-O:O'}trimethyltin(IV) (Tahir et al., 1997b) have been published which are related to the title compound due to coordination around the tin.
The Sn atom has a distorted trigonal bipyramidal geometry. The basal plane consists of three methyl groups and the apical position are occupied by the O-atoms of two carboxylate ligands. The Sn atom is 0.1082 (20) Å out of the equatorial plane towards the more strongly bound O1 atom. The Sn—O bond lengths are significantly different [Snl–O1 2.197 (2) and Snl–O2 2.359 (2) Å]. In the asymmetric unit the acetato moiety A (O1/C4/C5/O2), benzene ring B (C6–C11) are planar with r.m.s. deviation of 0.0020 and 0.0059 Å, respectively. The dihedral angle between A/B is 57.727 (115)°. The nitro group is oriented at a dihedtal angle of 36.896 (298)° with the benzene ring. The molecules form one-dimensional polymeric chains (Fig. 2) running along the crystallographic b-axis. There exist a π–π interaction between Cg1···Cg1i [i = 1 - x, -y, -z] at a distance of 3.9131 (19) Å, where Cg1 is the centroid of benzene ring.
