It is shown that the maximum bond energy structure method can be extended by using the maximum overlap symmetry hybrid orbital procedure. The extended method can be applied to not only σ-bond systems, but also other complex systems involving multiple and/or conjugated bonds. The method is much easier to perform than the ab initio and some other semi-empirical methods, and the optimized molecular geometries are in good agreement with the experimental data and can compare well with the ab initio and MINDO/3 results, which shows that the extended method is reasonable and may be feasible in even very large systems.
