Article abstract of DOI:10.1039/DT9800001550

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) Angstroem.Crystals of the complex (2) are triclinic, space group P1, with a=10.219(3), b=10.436(3), c=8.452(2) Angstroem, α=91.83(3), β=111.28(4), and γ=101.30(3)o.Full-matrix least-squares refinement has given an R of 0.050 for 475 reflections for (1) and of 0.051 for 2564 reflections for (2).Complex (1) is monomeric with four-co-ordinate thallium and a C-Tl-C angle of 148o; (2) is dimeric with bridging oxygen atoms giving five-co-ordination around the thallium atom and a C-Tl-C angle of 163o.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.
