Abstract:
The reactions of the organoantimony and organobismuthoxides [LSbO] 2 ( 1 ) and [LBiO] 2 ( 2 ), where L = [2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 ] – , with selected organophosphonic acids in a 1:4 molar ratio gave molecular organoantimony and organobismuth phosphonates LM[OP(R)(O)(OH)] 2 [M = Sb, R = Et ( 3 ), Ph ( 4 ), t Bu ( 5 ); M = Bi, R = t Bu ( 8 )]. Similarly, the reactions of 1 and 2 with t BuP(O)(OH) 2 in a 1:2 molar ratio resulted in LM[O 2 P( t Bu)(O)] [M = Sb ( 6 ), M = Bi ( 9 )]. Reactions of 6 and 9 with EtP(O)(OH) 2 yielded mixed phosphonates LM[OP(Et)(O)(OH)][OP( t Bu)(O)(OH)] [M = Sb ( 7 ), M = Bi ( 10 )]. All compounds were characterized by elemental analysis, ESI mass spectrometry, 1 H, 13 C and 31 P NMR spectroscopy and IR spectroscopy. Molecular structures of compounds 4 , 5 , 8 and 9 were determined by using X‐ray single‐crystal diffraction in the solid state. Secondary phosphonates 4 , 5 and 8 form weakly bonded dimeric units through hydrogen bridges of the type PO–H ··· O=P. On the other hand, compound 9 is trimeric in the solid state with the central 12‐membered ring formed by three LBi[O 2 P( t Bu)(O)] building blocks through intermolecular Bi ··· O=P contacts.
