Abstract

The compound (Ni(C5H5NO)6)(NO 3)2 crystallises in the space group R3 with the metal atom at the centre of the unit cell, which imposes a centre of inversion, and a three-fold rotation axis at the metal atom. The NO3 - groups are positionally disordered. Susceptibility measurements at 1.60K on oriented single crystals of (Ni(C5H5NO) 6)(NO3)2 in applied fields clearly shows a singlet-doublet crossing at H1c=46.2+or-1.5 kOe. Susceptibilities at zero field are also presented. The data analyses yield D/kB approximately=5.69K for the singlet-doublet separation and zJ/kB approximately=-1.45K for the (subcritical) antiferromagnetic interaction.
