Transition metal complexes of the type [M{4,5-(P(E)Ph2) 2tz}2(thf)n] [tz = 1,2,3-triazole; M = Cu, n = 2, E = S(3); M = Cu, n = 0, E = Se(4); M = Zn, n = 2, E = S(5); M = Cd, n = 2, E = S(7), Se(8); M = Pd, n = 0, E = S(9), Se(10)] and [Zn2{4,5-(P(Se) Ph2)2(tz)}4](6) were obtained by reacting [K{4,5-(P(E)Ph2)2tz}] with MX2 (M = Cu, Zn, Cd, X = Cl or M = Pd, X = AcO) in a 2:1 M ratio. The structures of these compounds were investigated by IR, 1H and 31P NMR spectroscopy, as well as by elemental analysis. The molecular structures of 3, 4, 5-10 were determined by single-crystal X-ray diffraction. In addition, during the crystallization process of 4, single crystals of 4a were obtained showing a structure where the replacement of a selenium atom from the non-coordinated PSe moiety by an oxygen atom gives a mixed oxygen-selenium complex. All the compounds exhibit MEPCN heterocycles as a common structural feature but in the case of 6 a bimetallic arrangement with a scorpionate-like coordination mode is also observed.

The novel ligand 4,5-bis(diphenylthiophosphinoyl)-1,2,3-triazole, LT-S2H, has been synthesized, converted to the triethylamine salt, and to the palladium complexes Pd[LT-S2]2 and Pd[LT-S2][η3-methallyl]. Structures of LT-S2H, of its 2-acetyl derivative, of Pd[LT-S2]2 and Pd[LT-S2][η3-methallyl] were determined by X-ray crystallography. In the last two complexes the LT-S2 ligand was N,S-bonded.
