Abstract :
The ESR spectrum of the mixed coinage metal cluster Au2Ag in a perdeuteriobenzene (C6D6) matrix prepared using a rotating cryostat is reported. The cluster has the magnetic parameters g = 1.9292 ± 0.0001, a(2Au197) = 39.7±0.05 mT and a(1Ag(107+109)) = 1.3 ± 0.05 mT. These indicate a static obtuse triangular structure with a 2B2 ground state in C2v symmetry, with two gold nuclei at identical terminal positions.
