Within the Chlorsulfuron References network structure, there are two types of hydrogen bond, namely, C-H and O-H (presented in Figure four and Table S2). In addition, two kinds of intermolecular and C-H interactions exist in the arrangement; as shown in Table S3, the hydrogen bonds and interactions enriched the architecture of 1. The distances amongst the center of gravity on the rings (Cg g distance) ranges from three.730 to 3.742 plus the distances amongst C atom and Cg on the rings (C g distance) variety from 3.371 and 3.850 Frequently, the co-existence of [268] C-H interactions and hydrogen bonds tends to make complicated 1 turn out to be moreFigure 4.
