Synthesis and characterization of Li(I)–M(II) (M = Co, Ni) heterometallic complexes as molecular precursors for LiMO2
摘要:
Lithium-containing heterometallic complexes with cobalt (Li2Co2(Piv)(6)(2,4-Lut)(2) (2, Piv is the pivalate anion) and Li2CO2(O2CCH2Bu)(6)(2,4-Lut)(2) (3)) and with nickel (Li2Ni2(Piv)(6)(DME)2 (4) and Li2Ni2(Piv)(6) (2,2'-bpy)(2) (5)) were synthesized. The structures of the complexes were established by X-ray diffraction. The magnetic properties of complexes 2 and 4 were studied. The thermal behavior of compounds 2, 3, and 5 was investigated. It was shown that the compounds under study can be used as molecular precursors for the synthesis of lithium cobaltate and nickelate. (C) 2010 Elsevier Ltd. All rights reserved.
