Abstract
The 1∶1 methylmercury complex withl-alanine belongs to the orthorhombic space groupP212121. The unit cell of dimensionsa=5.763(3),b=6.851(6),c=18.75(2) Å contains four molecules. The structure was refined on 584 nonzero reflections toR=0.050. The methylmercury ion has replaced an ammonium proton and is linearly bonded to the nitrogen atom. Mercury is also involved in secondary inter- and intramolecular contacts with carboxylate oxygen atoms. Infrared and Raman spectra of the amino-deuterated complex are discussed and compared with those of the undeuterated compound. A correlation is found between backbone conformation and the pattern ofυ Hg-N andυ Hg-C bands in the Raman spectra.
