WebbComplexes in which naphthalene 2 ˉ or anthracene 2 ˉ anions are sandwiched between two ( DIPeP BDI)Ca + cations were isolated. The low-valent complex ( DIPeP BDI*)Mg-Ca ( DIPeP BDI) could not be isolated due to its high reactivity. There is, however, strong evidence that this heterobimetallic compound is a fleeting intermediate. Webb1 okt. 1995 · A thermodynamic analysis of the phase equilibria in the Pb-Sn-Sb ternary system was conducted. A regular solution approximation based on a two-sublattice model was adopted to describe the Gibbs energy of formation of the individual phases in the binary and ternary systems. In the case of some component binary systems, the effect …
