Trigonal Bipyramidal

Stable germanium(II)-dithiocarbamate complexes Ge[S2C(NR2)]2 (R = Me, Et) have been obtained from GeCl2 · dioxane and Na[S2C(NR2)]. As an intermediate, Ge(Cl)[S2C(NEt2)] also could be isolated. Likewise, Ge[S2PMe2]2 was synthesized from GeCl2 · dioxane and Na[S2PMe2] and characterized by X-ray structure analysis. The germanium atom acts as a spiro-center for four sulfur atoms in a distorted ψ-trigonal bipyramidal configuration which is established by two anisobidentate dithiophosphinate ligands. The axial Ge—S bonds are significantly longer (mean: 2.722 A) than the equatorial ones (mean: 2.415 A). The variation in the axial bonds is more pronounced (0.058 A) than in the equatorial (0.013 A) Ge—S bonds, but this effect is much smaller than in the comparable Ge[(PMe2)2CPMe2]2 complex.

Formation of partially fluorinated imidazoles 6 from 4,4-bis(trifluoromethyl)-1,3-diazabuta-1,3-dienes 1 in the presence of low-valent metal compounds is shown to proceed via a [4+1] cycloadduct in the case of germanium(II)-chloride. The resulting germole 3 has been characterized by X-ray analysis. The five-membered ring is planar and the germanium atom adopts tetrahedral configuration.

Spectroscopic Characterisation

Compounds of the type, [Ge(OPri)4-n(OCH2CH2OR)n], (where R = Me, Et, n-Bu and n = 1-4) have been synthesised in high yields by the interactions of germanium tetraisopropoxide with alkoxyalkanols (HOCH2CH2OR) in different stoichiometries in refluxing anhydrous benzene, and are monomeric in refluxing benzene. All these compounds can be purified by distillation under reduced pressure. IR and NMR (1H and 13C) spectral studies indicate a tetrahedral geometry around the germanium atom.
