The bu metal substituted diarfline species |CpFe(CO)2]2(C6H2Aa)2 (3) synthesized frum [CpFd(CO)2]2 and e-(C6H5As)5 crystallizes in the centrosymnietric monoclmic space gioup P21/c [C1/25. No 14] with a = 6.534(2) ?, b β = 11.91 ?, e = 17.529 (5) ?, β = 99,60 (2) ?, V = 1263.9 ?a, and A = 1.73 g cm-3 for Z = 2 (mol wt 657 98(. Diffraction data were collected with a Niculft R3 diffrfictompter, and the structure was refined to RF = 6.60% for 1579 reflecuotis with 3° a new class of bridged dimidBflr metal romplesps.
