Lewis base character of hydroxygermylenes for the preparation of heterobimetallic LGe(OH)M systems (M=Fe, Mn, L=HC[(CMe)(NAr)]2, Ar=2,6-iPr2C6H3)

LGeOH (1; L = HC[(CMe)(NAr)](2), Ar = 2,6-iPr(2)C(6)H(3)) reacted with iron and manganese complexes to give LGe(OH)Fe(CO)(4) (2) and LGe(OH)Mn(CP)(CO)(2) (3; Cp = cyclopentadienyl). Compounds 2 and 3 were characterized by IR, multinuclear NMR, EI-MS, and single-crystal X-ray diffraction.
