Abstract:

Heat capacities and low field magnetic susceptibilities of single crystal NiSnCl6-6H2O and six other isostructural Ni2 compounds have been measured down to 0.05 K. In NiSnCl6-6H2O, NiPdCl6-6H2O, NiPtCl6-6H2O, NiPtBr6-6H2O and NiPtI6-6H2O the S 1 ground state of the NiH2O62 complex is split into a lower singlet and an upper doublet. Spin coupling in these compounds is subcritical and of antiferromagnetic sign. In NiTiF6-6H2O and NiZrF6-6H2O the zero field splitting leaves the doublet lowest, interactions are ferromagnetic, and ferromagnetic ordering occurs below Tc0.17 K.
