  Structure and properties of dibutylamine complexes with aluminum and gallium halides: The role of hydrogen bonds

  摘要：

  Reactions of aluminum and gallium halides MX3 (M = Al, Ga; X = Cl, Br) with dibutylamine in benzene solutions were studied by calorimetry, dielectrometry, and cryoscopy. The formation of molecular complexes (Bu2NHMX3)-M-. (1:1), 2Bu(2)NH(.)MX(3) (2:1) and 6Bu(2)NH(.)MX(3) (6:1) was established. In the 1:1 complexes, the donor-acceptor bond is formed by the lone electron pair of the nitrogen atom and a vacant orbital of the metal. Hydrogen bonds strongly affect the structure and properties of the 2:1 and 6:1 complexes. Complexes of the composition 2Bu(2)NH(.)MX(3) are present in solution as six-membered metallacycle with a four-coordinate metal atom, and the second amine molecule linked with the complex (Bu2NHMX3)-M-. with N-(HN)-N-... and N-(HX)-X-... hydrogen bonds.
