Metal Complexes of Biologically Important Ligands, LXVIII[1]. - Organometallic Asparaginato Cobalt Complexes as Ligands for Alkaline IonsThe trischelate complexes of the dianion of aspartic acid and β-methylaspartic acid (η5-C5Me5)] (R = H, Me) form adducts with alkali iodides MI (M = Li, Na, K). The polymeric structure of (η5-C5Me5)Co(L-asp.-2H+)KI (1c) was determined by X-ray diffraction. In the crystal of 1c the potassium ions are surrounded by five oxygen atoms of the carboxylate groups whereby two oxygen atoms form bridges between two K+ ions. Similarly, trischelate complexes 4 and 5 have been obtained from (η5-C5Me5)Co(CO)I2 and 2,3-diaminopropionic, 2,4-diaminobutyric acid, and asparagine, respectively.
