摘要：Chlorantraniliprole is one of the most widely used broad-spectrum pesticides. This paper studied three solid forms of chlorantraniliprole, among which two novel solvates were introduced, as well as their crystal structures. Form 2 and form 3 are defined as DME solvate in the triclinic space group P(-)1 (Z=4) and pyridine solvate in the triclinic space group P(-)1 (Z=2), respectively. All of the three forms were characterized and identified by powder X-ray diffraction, thermal analysis (DSC and TG), vibrational spectroscopy (IR and Raman), electron microscopy and particle size distribution. Solid-state stability and transformation relationship of the solid forms were also investigated. Besides, the insecticidal activities of form 1 and form 2 were examined. (C) 2018 Elsevier B.V.
