Abstract
Reaction of mercury(II) acetate, 2-(lH)-pyridone and hydrated M(NO3)3 (M = Y, Ce, Pr, Nd, Eu, Gd, Dy, or Er) in methanol gave the heterometallic complexes MHg2L4(NO3)3. Use of 4-methyl-2-(lH)-pyridone afforded a similar series of Hg/lanthanide compounds and the complex ThHgL4(NO3)4, and several analogues with 6-methyl-2-(lH)-pyridone and 4-(lH)-pyridone were also isolated.
