Synthesis and Reactivity of the Neutral Pyrazolate Complexes [M2{CH2C6H4P(o-tolyl)2-κC,P}2(μ-Rpz)2] (M = Pd, Pt; Rpz = Pz, 3,5-dmpz, 4-Mepz) toward AgClO4. Molecular Structure of [Pt2Ag{CH2C6H4P(o-tolyl)2-κC,P}2(μ-4-Mepz)2]ClO4
摘要:
The neutral compounds [Pt-2{CH2C6H4P(o-tolyl)(2)-kappaC,P}(2)(mu-Rpz)(2)] (Rpz = pz (2a), 3,5-dmpz (2b), 4-Mepz (2c)) react with AgClO4 in a 1:1 molar ratio to give the trinuclear compounds [Pt2Ag{CH2C6H4P(o-tolyl)(2)-kappaC,P}(2)(mu-Rpz)(2)]ClO4 (Rpz = pz (4a), 3,5-dmpz (4b), 4-Mepz (4c)), which contain two Pt-Ag bonds. The reaction of [Pd-2{CH2C6H4P(o-tolyl)(2)-kappaC,P}(2)(mu-3,5-dmpz)(2)] (3b) with AgClO4 renders [{Pd-2(CH2C6H4P(o-tolyl)(2)-kappaC,P)(2)(mu(3)-3,5-dmpz-N,N',C-4)(2)Ag(eta(2)-mu(2)-ClO4)}(2)] (5), a palladium/silver compound with an unprecedented dmpz bridging ligand eta(1)-bonded to the Ag centers, a coordination mode involving only the C-4 atom of each dmpz ligand.
