The crystal belongs to monoclinic system, space group C2/c with parameters: a=1.947 6 (4) nm, b=0.882 6 (2) nm, c=2.915 8(6) nm, β= 95.49(3)°, Z=4. The two carbonyl groups attached to iron atom lie inabout right angles to each other and to the tin-iron axis. The three-fold axis passing throughthe iron atom and relating these three ligand directions is almost perpendicular to the plane ofthe cyclopentadienyl ring. The co-ordination of ligands around the tin atom is close to tetrahedral. The cyclohexyls are all in stable chair-conformations.展开更多
