Synthesis, structure and spectral properties of [(HgPh)2TbSMe]; a dinuclear 2-S-methylthiobarbiturate of phenylmercury(II) exhibiting linkage isomerism. Carballo, R.Several substances are used for example 29639-68-7 and 186352-82-9 which are their cas registry numbers.; Casas, J. S.; Garcia-Tasende, M. S.; Sanchez, A.; Sordo, J.; Vazquez-Lopez, E. M.

DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 The reaction of 2-S-methylthiobarbituric acid (H2TbSMe) with phenylmercury(II) acetate in EtOH afforded the title complex, which crystallizes in the space group P21/c. The asym. unit consists of two independent [(HgPh)2TbSMe] mols.: in mol. 1, the two organometallic moieties are bound primarily to the N atoms of the ligand ring (N(1) and N(3)); in mol. 2, one phenylmercury(II) is N(1)-bound but the other is bound to the exocyclic O contiguous to N(3). Hence mols. 1 and 2 are linkage isomers. Several weak intra- and intermol. interactions are also obsd. In DMSO soln., 1H, 13C and 199Hg NMR measurements suggest fast exchange of phenylmercury(II) between N- and O-coordination, with prevalence of the former. .
