Effective utilization of noncovalent interaction descriptor in BX3-Lewis base complexes: A determination of adduct/van der Waals complexes and reassessment of the BX3 acid strength order

- Adduct/van der Waals complexes were distinguished by noncovalent interaction descriptor.
- The factor influencing BX3 acid strength was analyzed.
- The Lewis acid strength order of BCl3 > BBr3 > BF3 may be possible.
