Abstract
The crystal structures of the title complexes, (1) and (2) respectively, are reported. Complex (1) crystallises in the orthorhombic space group Pca21 with a= 20.399(5), b= 8.177(6), and c= 10.699(4)Å. Crystals of the complex (2) are triclinic, space group P, with a= 10.219(3), b= 10.436(3), c= 8.452(2)Å, α= 91.83(3), β= 111.28(4), and γ= 101.30(3)°. Full-matrix least-squares refinement has given an R of 0.050 for 475 reflections for (1) and of 0.051 for 2 564 reflections for (2). Complex (1) is monomeric with four-co-ordinate thallium and C–Tl–C angle of 148°; (2) is dimeric with bridging oxygen atoms giving five-co-ordination around the thallium atom and a C–Tl–C angle of 163°. Factors determining the degree of polymerization for this class of thallium compounds are discussed, and 13C n.m.r. spectra of (1) and (2) are reported.Keywords
