Popis:	The principal magnetizations of [Ni(pyo)6][BF4]2 and average magnetization of [Ni(pyo)6][ClO4]2 have been measured from 2 to 20 K at magnetic-field strengths up to 50 kG (pyo = pyridine N-oxide). The magnetization of [Ni(pyo)6][BF4]2 parallel to the c axis can be reproduced by the spin-Hamiltonian parameters g∥= 2.28 and D= 5 cm–1. The perpendicular magnetization is reduced by antiferromagnetic exchange interactions with TN < 2 K. The average magnetization of [Ni(pyo)6][ClO4]2 is similar to that of the tetrafluoroborate salt indicating that the exchange interactions in the two compounds are also similar.
