“…Aspartic acid (8) is an amine-derivative of succinic acid. The crystal structure of Pb(Hasp)(NO 3 ) has a 3D framework, formed by polymeric chains oriented along the three crystallographic axes [46]. The Pb atoms are coordinated by six oxygen atoms, five from the carboxylate groups of the organic ligand Table 2).…”

“…The solution was heated at 95-100°C for 60 min. On slow cooling to room temperature in the filtration flask colorless needle-like crystals of [Pb(OH 2 ) 2 (Ile) 2 Pb-Val-Ile. A stirred mixture (10 min) of L-valine (5.00 Â 10 -3 mmol, 0.586 g) and L-isoleucine (5.02 Â 10 -3 mmol, 0.658 g) in water (20 mL, pH 6.21) was added to a solution of Pb(NO 3 ) 2 (5.00 Â 10 -3 mmol, 1.656 g) in water (20 mL stirred 10 min, pH 3.73) resulting in a clear, colorless solution with a pH of 4.34.…”

Complexes of lead with L-phenylalanine, L-isoleucine, L-valine, or L-arginine have been isolated from reaction mixtures containing lead nitrate and the respective amino acid in acidic aqueous solution. The compounds have been comprehensively characterized using X-ray crystallography, solid state NMR spectroscopy and solution state NMR spectroscopy, IR and Raman spectroscopies, and electrospray ionization mass-spectrometry. The solid state structures of lead-phenylalanine, lead-valine, and lead-valine-isoleucine complexes show a lead center coordinated by two amino acid ligands, while the lead-arginine complex is a cluster involving two lead centers and three arginine molecules. The structural, spectroscopic, and spectrometric characterization of the complexes provides a basis to establish a fundamental understanding of heavy metal-amino acid interactions.

The study of main-group metal elements and their coordination complexes with amino acids is an important theme in coordination chemistry, but it has often been overshadowed by the intense interest in transition-metal coordination complexes. In recent years, there has been a growing interest in main-group compounds, extending across all members of sand p-blocks in the Period Table, which has resulted in the discovery of numerous new classes of compounds with previously unknown structures and bonding. Among these achievements, the coordination complexes of main group metals with amino acid ligands are especially notable. As a kind of functional ligand, amino acids set up a bridge of interdisciplinary subjects between coordination chemistry and biology. The research on coordination chemistry of main group metals with amino acid ligands will benefit to understanding of the biological effects of main group metals; developing new medicine; designing and synthesizing functional and environmental friendly materials. To achieve these targets, the structural information of these new coordination complexes is very important and it provides fundamental knowledge for more extensive investigation in the future. Therefore, this review focus on the single crystal structures of the coordination complexes of main group metals with amino acid ligands based on X-ray crystallography. Literature coverage is around the last 15 years and ends to May 2013 although some older works are also included for comparing. Specially, this article has been written to commemorate 2014 the International Year of Crystallography declared by United Nations.
