Figure 2
(a) Hydrogen-bonding inter­actions between copies of 3 along the a and b axes. (b) C—O and H—O distances suggestive of a potential C—H⋯O hydrogen bond along the a axis. N—H⋯O distances for the H1B⋯O3 hydrogen bond are included for comparison. (c) Measured distances and electrostatic coloring between H4A, C7, and C8 used to explore a potential C—H⋯π inter­action within the ab plane mol­ecular layers. Partial charges were generated within UCSF Chimera (Pettersen et al., 2004BB16) using the Amber ff14SB forcefield in Antechamber (Wang et al., 2006BB20) with the semi-empirical AM1 − BCC method and color coded with pink for negative charges and light blue for positive charges.
