USE OF A COORDINATION COMPLEX OR COMPOUND FOR THE MEASUREMENT OF TEMPERATURE

Use for measuring temperatures of a coordination complex (11) presenting formula I, Wherein M1, M2, M3, M4, M5 are cho- S sen, each independently of the others, in the group consisting NWL‘M, of: Cu], Ag], Au], Pd”; n is equal to the sum of the oxidation states of M1, M2, M3, M4, M5 minus 3; ll represents a respec- . tive portion of each tridentate ligand having the formula III in which R1 is chosen in the group consisting of: Ph, Cl-C4 alkyl, halo-alkyl Cl -C4 substituted phenyl; R2 is chosen in the group consisting of: Ph, Cl-C4 alkyl, Cl-C4 halo-alkyl-, sub- 3 stituted phenyl; R3 is chosen in the group consisting of: Cl-C18 alkyl, benzyl, substituted benzyl, Cl-C2O hydroxy alkyl, Cl-C2O alkoxy silane.
