In the title polymeric coordination compound, [Sn(CH3)3(C20H12O4P)]n, the Sn atom exhibits a distorted trigonal-bipyramidal coordination geometry with the phosphate O atoms of the 1,1′-binaphthyl-2,2′-diyl phospho­nate ligands in axial positions and equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 1,1′-binaphthyl-2,2′-diyl phospho­nate ligand, forming a one-dimensional chain structure parallel to the b axis.

Comment top

In recent years, organotin complexes have been attracting more and more attention due to their wide industrial applications and biological activities (Dubey & Roy, 2003). 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, which is shown in Fig.1, forms an extended one-dimensional chain structure arising from Sn—O bridges formed by the 1,1'-binaphthyl-2,2'-diyl phosphonate ligands. The Sn—O bond distances in the compound (Sn(1)—O(3) = 2.253 (3) Å; Sn(1)—O(4)#1 = 2.262 (3) Å; symmetry code (#1): #1 - x,y + 1/2,-z + 3/2) are comparable to those found in related organotin carboxylates (Ma et al. 2006, Wang et al. 2007). The Sn atom assumes a slightly distorted trigonal-bipyramidal coordination geometry, provided by and three methyl groups in the equatorial positions and two O atoms of symmetry related phosphate groups in the axial positions.

Experimental top

1,1'-Binaphthyl-2,2'-diyl phosphonate acid (1 mmol) and sodium ethoxide (1.2 mmol) were added to a stirred solution of benzene (30 ml) in a Schlenk flask and stirred for 0.5 h under nitrogen. Trimethyltin chloride (1 mmol) was then added to the reactor and the reaction mixture was stirred for 12 h at room temperature. The resulting clear solution was evaporated under vacuum. The product was crystallized from a solution of diethyl ether to yield colourless blocks of the title compound (yield 83%). Anal. Calcd (%) for C23H21O4P1Sn1 (Mr = 511.06): C, 54.05; H, 4.14. Found (%): C, 54.51; H, 4.64.

Refinement top

The H atoms were positioned geometrically, with methyl C—H distances of 0.96Å and aromatic C—H distances of 0.93 Å, and refined as riding on their parent atoms, with Uiso(H) = 1.2 Ueq(Caromatic) or 1.5 Ueq(C) for the methyl groups.
