Synthesis, properties and NMR spectra of organobismuthanes RBi2 (R= Me, Ph, pTol; R'= Me, Et, iPr, Ph) and R2BiS2P(OR')2 (R = Ph, pTol; R' = Me, Et, iPr, Ph) are discussed.Tris(O,O'-diorganodithiophosphato)bismuthanes Bi3 (R= Me, Et, iPr, Ph) are generated from R3Bi (R= Me, Et) and corresponding phosphorus compound HS2P(OR)2 (R = Me, Et, iPr, Ph) in yields of about 50percent.Crystals of Bi3 are monoclinic (space group P21/c) with the following cell parameters: a = 1509.6(6), b = 786.5(4), c = 1909.5(1) pm, β = 109.907(6) deg, V = 2133.21(5)E6 pm3, Z = 4.The compound appears to be dimeric in the solid state state resulting in the formation of an eight membered ring system.Key words: Bis(O,O'-diorganodithiophosphato)organobismuthanes, (O,O'-Diorganodithiophosphato)diorganobismuthanes, tris(O'O'-diorganodithiophosphato)bismuthanes, NMR spectra, crystal structure, secondary bonding, PS2-chelation.
