title: Synthesis and molecular structure of [[(HBpz(3))Rh(PPh(3))(mu-Cl)(2)](2)Ag]BF(4) (Hpz = pyrazole), a heterotrinuclear Rh(2)Ag compound with square-planar silver(I).
abstract: Reaction of [(HBpz(3))RhCl(2)(PPh(3))] (Hpz = pyrazole) with silver salts AgA (A = BF(4), NO(3), SbF(6)) affords the unexpected heterotrinuclear compounds [[(HBpz(3))Rh(PPh(3))(mu-Cl)(2)](2)Ag]A (A = BF(4) (1), NO(3) (2), SbF(6) (3)). The compounds have been fully characterized by IR, (1)H, (31)P[(1)H], and (13)C[(1)H] NMR spectroscopy and FAB(+) mass spectrometry. The solid structure of compound 1 was determined by single-crystal X-ray diffraction. The cation consists of two (HBpz(3))RhCl(2)(PPh(3)) units bonded to a silver atom through two double mu-Cl bridges in an unusual distorted square-planar arrangement.
