Abstract
Structural and thermodynamic characteristics of donor-acceptor complexes LA·E′H2EH2·LB(E = B, Al, Ga; E′ = P, As, Sb; LB = SMe2, NMe3);LA- Lewis acids of group 13 elements ER3 (E = B, Al, Ga; R = H, Me, F, Cl, Br, I, C6F5) and transition metal carbonyls Fe(CO)4, M(CO)5, (M = Cr, Mo, W), CpMn(CO)2 were computed by quantum chemical B3LYP-D3/def2-TZVP method. It is shown that removal of the Lewis base is less endothermic than removal of Lewis acid. Stability trends of the complexes depending on group 13/15 elements and Lewis acids were established. Tungsten pentacarbonyl has the highest stabilization effect.
