A material consisting of nanometric particles consisting essentially of a compound that corresponds to the formula ** (See formula) ** in which: - L represents a 1,2,4-triazole ligand bearing an R substituent on nitrogen in position 4; - X is an anion that has the valence x, 1 <= q x <= q 2; - Y is an anion other than X that has the valence x '', 1 <= q x '' <= q 2; - R is an alkyl group or an R1R2N- group in which R1 and R2 each represent H independently of the other, or an alkyl radical; - M is a metal that has a 3d4, 3d5, 3d6 or 3d7 configuration, except Fe; - 0 <= q and <= q 1; - 0 <= q z <= q 2; - 3 <= q w <= q 1500. |
