Tetrel bond cooperativity in open-chain (CH3CN)n and (CH3NC)n clusters (n = 2-7): An ab initio study

- Cooperative effects between tetrel bond interactions in linear (CH3CN)2-7 and (CH3NC)2-7 clusters are studied.
- Cooperative effects enhance the covalency of C⋯N and C⋯C interactions.
- (CH3NC)n clusters present a larger cooperativity effects than (CH3CN)n ones.
