Synthesis and Structures of Triphenylbismuth Bis[3-(2-Furyl)Acrylate] Ph3Bi[O2CCH=CH(C4H3O)]2 and Triphenylbismuth Di-meta-nitrocinnamate Ph3Bi(O2CCH=CH–С6H4NO2-m)2

Resumo

Triphenylbismuth bis[3-(2-furyl)acrylate] Ph₃Bi[O₂CCH=CH(C₄H₃O)]₂ and triphenylbismuth di-meta-nitrocinnamate Ph₃Bi(O₂CCH=CH–C₆H₄NO₂-m)₂ were synthesized and studied by X-ray diffraction. The crystal structures (sp. gr. P1, Z = 2; sp. gr. P2₁, Z = 2, respectively) contain one and two tetrahydrofuran solvent molecules, respectively, per bismuth complex. The bismuth atom has a trigonal-bipyramidal coordination geometry. Additional weak Bi···O interactions (2.748–2.835 Å) cause large angle distortions in the equatorial plane of the trigonal bipyramid.
