Abstract The geometry of small, silica supported Ni clusters has been studied using quantum mechanical cluster calculations and energy minimization techniques. A strong distortion from a spherical particle shape was found when the metal was in contact with the support. This resulted in a smaller average coordination number compared with isolated metal particles and in an increase of the interatomic distance for small particles.
