We report 1H and 23Na nuclear magnetic resonance (NMR) and relaxation measurements in two variants of the V6 cluster with formula [CH 3H 6] 4Na 2[H 4V 3L 2P 4O 4]ṡ14H 2O and Na 6[H 4V 3L 2P 4O 4]ṡ18H 2O, respectively. Both the NMR linewidth and the spin-lattice relaxation (NSLR) data can be explained semiquantitatively by assuming a dipolar coupling between the proton (sodium) nuclei and the three V(IV) magnetic moments forming an almost equilateral triangle with nearest neighbor antiferromagnetic exchange interactions. From the temperature dependence of the 23Na NSLR we obtain the value of the two gaps separating the lower energy total spin states.
