Probing the distinct nanomechanical behaviour of a new co-crystal and a known solvate of 5-fluoroisatin and identification of a new polymorph

Abstract

Crystalline forms of 5-fluoroisatin have been characterized by thermal, structural, and mechanical methods. The hardness and elastic modulus of the DMSO solvate is significantly higher than those of the picolinic acid co-crystal of 5-fluoroisatin.
