An Unprecedented Coordination Mode of the Tris(pyrazolyl)methane Donor Set in {[Ph2(O)POCH2C(pz)3Ag]2(THF)2}(BF4)2: kappa2-kappa1, Bimetallic, Nsigma/Npi Chelating
The structure of the compound {[Ph2(O)POCH2C(pz)3Ag]2(THF)2}(BF4)2 (pz = pyrazolyl ring) revealed a new coordination mode for the tris(pyrazolyl)methane donor set: two pyrazolyl rings bridging the same two silvers atoms using normal -type orbitals on the nitrogen donor atoms while the third pyrazolyl ring coordinates side-on to one of the silver atoms with a nitrogen-based -type orbital. The dimeric arrangement is also supported by a weak silver-silver
