Sequence of Structural and Magnetic Phase Transitions in (NO)Mn(NO).

New nitrosonium manganese(II) nitrate, (NO)Mn(NO), has been synthesized and structurally characterized. In the temperature range of 45-298 K, the crystal is hexagonal (centrosymmetric sp. gr.

Ising-like Magnetism in Quasi-Two-Dimensional Co(NO)·2HO.

The appearance of electrically neutral water molecules in the structure of cobalt dinitrate dihydrate, Co(NO)⋅2HO, drastically changes its magnetic properties as compared to its waterless counterpart, Co(NO). The title compound shows Ising-like behavior reflected in its thermodynamic properties. It experiences long-range antiferromagnetic order at = 20.
