Abstract

The structure of the compound {[Ph 2(O)POCH 2C(pz) 3Ag] 2(THF) 2}-(BF 4) 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 σ-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 π-type orbital. The dimeric arrangement is also supported by a weak silver-silver interaction. This bonding description is supported by Fenske-Hall molecular orbital calculations.
