| Abstract: | Organotin and organolead derivatives of N-(2,4-dinitrophenyl)glycine (HDNG), R3MDNG (M = Sn, Pb; R = CH3, C6H5) and (C6H5)2Pb(DNG)2, have been prepared from R3MOH or (C6H5)2PbO]n and HDNG, respectively. (CH3)3PbDNG was also obtained from (CH3)3PbBr and TlDNG. According to spectroscopic data R3M groups in R3MDNG are essentially planar and are bridged by bidentate carboxylate groups of DNG. NH does not coordinate to M. Penta-coordination is also indicated by Mössbauer data of R3SnDNG. Also for (C6H5)2Pb(DNG)2 a chain structure but with hexacoordination of Pb is proposed. The compounds are monomeric in solution. |
