Soc. 1985, 107, 3902-3909) running on Silicon Graphics O2 workstation. Starting geometries were generated with molecular mechanics Genmol software (Pèpe, G. and Siri, D. Studies in Physical and Theoretical Chemistry 1990, 71, 93-101). Unconstrained geometry optimisation was performed using NEWTON minimiser with C. I. = 6, PRECISE and GNORM = 0.01 options turned on.
