The crystal structure, packing model and intermolecular interactions of MC_PP. (a) Unit cell of MC_PP. (b) 3D supramolecular packing model in the supercell with 4 × 1 × 1. (c) LSAM (1D) constructed by amalgamation of Synthon I (supramolecular synthon highlighted in purple interacting via O—H⋯N hydrogen bonds) and Synthon II (supramolecular synthon highlighted in green interacting via N—H⋯π hydrogen bonds). (d) Two-dimensional LSAM structure (highlighted in red) constructed by an arrangement of the LSAMs (1D) along the oac plane. Purple dotted lines and blue dotted lines represent π⋯H and O—H⋯N hydrogen bonding, respectively.
