Preparation and characterization of several azoxystrobin channel solvates
Azoxystrobin is an important strobilurins fungicide. Nine channel solvates of azoxystrobin were obtained for the first time and six of them could be crystallized in single crystals. The crystallographic data, unit cell porosity, Hirshfeld surface, and fingerprint plot were analyzed. These solvates ar...

Summary: | Azoxystrobin is an important strobilurins fungicide. Nine channel solvates of azoxystrobin were obtained for the first time and six of them could be crystallized in single crystals. The crystallographic data, unit cell porosity, Hirshfeld surface, and fingerprint plot were analyzed. These solvates are isostructural, azoxystrobin forming a host framework through intermolecular interaction and the guest solvent molecules located in channels. These solvates were stabilized by π⋅⋅⋅π interaction, CH⋅⋅⋅π interaction, and weak hydrogen-bonding interactions such as CH⋅⋅⋅O interaction and CH⋅⋅⋅C interaction. All solvates were characterized by PXRD, DSC, TG, FTIR, and FESEM, the stability of them were also examined. Moreover, because of the similarity of the channel solvates, solvent-replacement method could be used to prepare other solvates.
