tIn this work, ab initio calculations are performed to characterize cooperative effects between tetrel bondinteractions in linear (CH3CN)2–7and (CH3NC)2–7clusters. It is found that increasing the size of the clustersbrings about an important reduction in the tetrel bond distances, with the effect being most significant inthe central units. To shed more light on the cooperative phenomenon, molecular electrostatic potentialand electron density analyses are performed. According to interaction energy decomposition analysis,cooperative effects enhance the covalency of C· · ·N and C· · ·C interactions
