The 1 H NMR spectroscopic analysis and magnetization measurements were performed on TM2 2+ [Mo IV(CN)8].nH2O compounds (TM=Mn, Fe, Co, Ni, Cu, VO). The 1 H NMR signals reflect the magnetic moment of the TM ions (μP). The decay rates of FID signals increase as μP and the applied static rf field increase. The spin-lattice relaxation times at 27.7 MHz vary from 0.0187 ms (Mn) up to 0.45 ms (Cu). Magnetization measurements indicate ferrimagnetic ordering in Mn- and Co-compounds, and short range magnetic ordering in Ni-compound. Susceptibility data follows the Curie Weiss law above T=20 K.
