Intramolecularly formed pentacoordinated structures of triphenyltin esters of salicylic acid, o-anisic acid, and p-methylthiobenzoic acid

Triphenyltin esters were formed by the reaction of bis(triphenyltin) oxide with salicylic acid, o-anisic acid, and p-methylthiobenzoic acid, 6-8, respectively. X-ray analysis revealed pentacoordinated structures containing Ph3Sn coordinated to the carboxylate group for 7 and 8. The structural distortion for each is a displacement from the tetrahedron toward a trigonal bipyramid. For 6, the structure contains an intramolecular oxygen atom interaction, in addition to hydrogen-bonding effects, with a resultant geometry close to tetrahedral. Infrared data confirm that carboxylate coordination occurs in solution. Factors influencing the appearance of the discrete five-coordinated form 6-8 relative to five-coordinated tin in a chain arrangement for related derivatives is discussed. For 6, the monoclinic space group P21/c (Z = 4) was obtained with a = 13.318 (6) ?, b = 12.113 (2) ?, c = 14.590 (4) ?, and β = 116.47 (3)°. Refinement gave R = 0.022 and Rw = 0.032. 7 crystallizes in the triclinic space group P1 (Z = 2) with a = 10.632 (2) ?, b = 11.452 (2) ?, c = 11.719 (2) ?, α = 62.86 (2)°, β = 71.95 (2)°, and γ = 62.31 (2)°. Refinement gave R = 0.024 and Rw = 0.041. For 8, the triclinic space group P1 resulted with a = 8.814 (1) ?, b = 9.816 (1) ?, c = 14.430 (3) ?, α = 89.39 (1)°, β = 80.19 (1)°, and γ = 68.89 (1)°. Refinement gave R = 0.025 and Rw = 0.040.
