Synthesis and Characterization of Transition Metal Compounds
In this research project, copper(II) coordination chemistry was investigated through synthesis and analysis copper (II) compounds containing organic ligands mimicking amino acids in metalloproteins. Diphenylacetic, I-Naphthoxyacetic, and 2-Napthoxyacetic were the carboxylic acids applied. The imines used were pyridine, 2,2'-bypridine, and 7-azaindole. Three novel copper coordination compounds, dinuclear C~(lNaphOCH2CO~ 4(NCCH3)2-2CH3CN, C~(Ph2CHCO~4(NC6HJ-2(N03)' and C~(Ph2CHCO~6(bpY)2(BF J-2CH3CN, were produced and characterized. Structural characterizations of these compounds in addition to several other copper (II) compounds were done using X-ray crystallography and infrared, electronic absorption, and Raman spectroscopy. Dinuclear paddle wheel structures were the most common structural arrangements identified. Inventories of the new structures were typified by different nuclearity, coordination, and binding m~des, specifically carboxylate shifts.
