The spectroscopic and solution properties of trimethylgermanium nitrate have been determined and compared with those of other known Group IV alkyl nitrates. The vibrational spectra show that the nitrato group is covalently bound to the germanium atom in a unidentate manner. Ultraviolet spectra and conductivity measurements indicate that the compound behaves as a 1:1 electrolyte in water and dimethylsulfoxide, but is a non-electrolyte in methyl cyanide, nitromethane, and ethyl acetate. Attempts to prepare methylgermanium trinitrate are also described.

Dimethylgermanium dinitrate has been prepared by the reaction of dimethylgermanium dichloride and nitrogen pentoxide in carbon tetrachloride. The properties of this compound have been investigated and compared with those of other known Group IVA alkyl nitrates. The vibrational spectra show that the nitrato groups are covalently bound to the germanium in a unidentate manner. Ultraviolet spectra and conductivity measurements indicate that the compound behaves as a 1:2 electrolyte in water and dimethyl sulfoxide but is a non-electrolyte in methyl cyanide, nitromethane, and ethyl acetate. The complexes Me2Ge(NO3)2•py and Me2Ge(NO3)2•2,2′dipy have been prepared and the infrared spectra of these compounds indicate considerable weakening of the germanium-nitrato bonds.

Tetrakis(methyl cyanide) complexes of Cu(I), Cu(II), and Zn(II) fluorosulfates have been prepared by reactions of anhydrous Cu(II) and Zn(II) fluorosulfates in methyl cyanide. The infrared spectra indicate a strong interaction between the fluorosulfate anion and the complex Cu(II) and Zn(II) cations. Conductivity measurements in methyl cyanide show strong association between the fluorosulfate anion and the dipositive cations. The Cu(I) compound is completely dissociated in methyl cyanide and, according to the infrared spectrum, shows no strong interaction with fluorosulfate anion.

Unambiguous Assignment

The vibrational spectra of some 1:2 trimethylphosphine adducts of the group IV tetrahalides, which contain ligands in a trans configuration, are examined in detail using perdeutero-trimethylphosphine to facilitate the assignment of all metal–halogen and metal–phosphorus stretching modes. Preparation of SiCl4•2PMe3 with a 1:1 mixture of P(CH3)3 and P(CD3)3 enables an almost unambiguous assignment of the spectrum of this adduct. Normal coordinate calculations for all adducts are reported.
