The following compounds have been prepared: >(2-n)> 5-C5H4)Fe(ν5-C5H5), E = O, R = R' = H, M = Mo, X = Cl or I, n = 0 or 1; E = NH, R = R' = H, n = 1, M = Mo or W, X = Cl; E = NH, R = Me, R' = H, n = 1, M = Mo, X = F, Cl, Br, I or OC6H11; M = W, X = Cl; E = NH, R = R' = Me, n = 1, M = Mo, X = Cl or I; M = W, X = Cl; R = NMe2, E = O, R = R' = H, M = Mo, X = Cl or I, n = 0 or 1; M = W, X = Cl, n = 1; E = NH, R = R' = H, n = 1, M = Mo, X = Cl or I; M = W, X = Cl>, >> (M = Mo, X = Cl or I; M = W, X = Cl) and >-4)>.Several of the ferrocenyl derivatives have been found to produce frequency doubling of radiation at 1907 nm, whereas the derivatives containing NMe2 or OEt groups do not.A single-crystal X-ray diffraction study has shown that -4>>*CH2Cl2 crystallises in the space group P21 and is isostructural with its molybdenum counterpart; in these crystals the molecules appear to be favourably oriented to produce phase matching.
