Reactions between the 1,3-bis(6-methylpyridin-2-yl) pyridine ligand L,C17H15N3 and LnIII(1a,1b,1c,1d) or a mixture of LnIII and CuII nitrates(2a,2b,2c,2d) resulted in a series of respectively novel mono-and heterodinu...
The combustion energies of fourteen solid complexes of lanthanide nitrate with alanine were determined. The standard enthalpies of combustion, Δ c,coor(s) H °, and standard enthalpies of formation, Δ f,co...
The combustion energies have been determined for the solid complexes, RE(Met) 4(NO 3) 3·6H 2O(RE=La~Nd, Sm~Lu), by means of a rotating bombicalorimeter. The standard enthalpies of combustion, ΔH c,co...
