Bismuth-amine complexes

These metal-amine complexes are stable toward moisture and are soluble in organic solvents, leading to liquid precursors with appropriate viscosities for their deposition on substrates. Metal oxide thin films have been prepared from these amine-based precursors, including complex oxide thin films of titanium or bismuth-based perovskites, among others. The molecular structures of the titanium-amine and bismuth-amine complexes synthesized in a solution are shown in Scheme 27.6 [25-27]. In addition, the dative bond from the nitrogen toward the metallic center incorporates new functionalities into these types of molecules, such as photosensitivity, that can be used for nonconventional methods of synthesis of metal oxide thin films. 

Simple amine adducts of the bismuth halides have been prepared, although many have not been structurally characterized. Adducts between amines and organobis-muth complexes have been better defined see Bismuth ... 

Elements of Group V contain arsenic in six-fold co-ordination, the changes are attributed to changes in the SAsS angle.692 The mass spectrometric behaviour of these compounds and the antimony and bismuth analogues has been studied,693 and Manoussakis et al. have obtained the corresponding diselenocarbamate complexes from the reaction of the trichloride with a secondary amine and carbon diselenide.594...
