We use quantum billiard with many scattering centers to describe conducting electrons properties in A_{n}C_{60} crystals, where A denotes alkali metal. We focus our attention on the A_{3}C_{60} crystal, for which we calculate the band structure, density of states, and conductivity for normal electrons. Conductivity shows linear dependence on temperature in this model, which agrees well with experimental data. We also discuss consequences of our results for superconductivity mechanism in A_{3}C_{60} and possibilities of analogous approach to describe electron properties in fused fullerenes and multiply connected carbon clusters.
