The solid-state reaction (reagent ratio Ni: LH = 1: 2) followed by recrystallization of the reaction product from a MeCN-THF mixture afforded crystals of the associate [Ni2L4]2·[NiCl2(LH)2(MeCN)2] containing four acetonitrile solvate molecules. Crystals of 2·4MeCN exhibit ferromagnetic properties at helium temperatures \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2006, 55 (12), 2181.pdf |
