“…The M -M bond distances differ from each other; while the mean Fe eq -Au^ bond distance in [52] of 2.734A is about 0.031 A shorter than that in [50], all remaining mean M -M bond distances are somewhat longer in [52] than those in [50]. The Fe eq -Fe eq bond distances are 2.864 (4) [53] or CIO 4 [54] anions. The geometry around the gold atom is in a distorted trigonal pyramidal coordination environment.…”

“…There are five coloured Fe 3 Au 2 complexes [50][51][52][53][54] which are the richest example in this series. The black complex [50] contains an Fe 3 Au 2 trigonal bipyramidal moiety with Au(l) and Fe (5) Structure of black (CO)9^3-S)Fe 3 Au 2 (PPh 3 ) 2 cluster [52] is similar to that of black (CO) 9 fa 3 -O)Fe 3 Au 2 (PPh 3 ) 2 [50].…”

“…The geometry around the gold atom is in a distorted trigonal pyramidal coordination environment. The gold atom lies ~ 0.3 [53] and 0.073A [54] out of the plane of the three phosphorus atoms. The mean Ag -Ρ bond distances are 2.380 [53] and 2.365 [54].…”
