Mt. Garland et al., MOLECULAR-ORBITAL CALCULATIONS OF BINUCLEAR SYSTEMS OF FE, CO AND NI DERIVATIVES OF PENTALENE, S-INDACENE AND AS-INDACENE, Journal of molecular structure. Theochem, 390, 1997, pp. 199-208
Extended Huckel calculations on a whole family of dinuclear complexes
of pentalene, s-indacene and as-indacene allow a general rationalizati
on of the structural and physical features of these compounds, mainly
based on their electron count.
