(a) The R44(12) ring in the three-dimensional hydrogen-bonded net of imide molecules. Four N—H⋯N imide/amide dimers are linked by N—H⋯O contacts. (b) The open R66(42) ring in the two-dimensional hydrogen-bonded net of amide molecules. Four amide/imide N—H⋯N-bonded dimers are linked by four N—H⋯O contacts. |
