The structure of five organoantimony compounds [C5H4Mn(CO)3]Sb (1), (4-Me2NC6H4)3SbI2 (2), Ph3Sb[OC(O)C6H3(NO2)2-3,5]2 (3), (3-MeC6H4)3Sb[OC(O)C6H3(NO2)2-3,5]2PhH (4), and (3-FC6H4)3Sb[OC(O)C6H3(NO2)2-3,5]2PhH (5) was determined by X-ray diffraction analysis. X-ray diffraction of the compounds was carried out on an automatic four-circle diffractometer D8 Quest Bruker (МоКα, λ = 0.71073 Å, 293 К.
