Silva, A. Sobral, J. Silva, A. Santos, S. Melo, A. Beja] A new substituted pyrrole, a precursor of meso-free-porphyrins, has been synthesised and characterised by single-crystal X-ray diffraction: monoclinic, P21/c with a=14.607(9)Å, b=5.136(2)Å, c=25.832(17)Å, β=108.14(5)°, Mr=349.41, V=1841.6(18)Å3, Z=4. The molecules are assembled in centrosymmetric dimers via strong N-H...O hydrogen bonds. The dimers are gathered into chains via C-H...π intermolecular interactions. Graphical abstract: The molecules in 4-benzyl-5-methoxymethyl-3-methyl-1H-pyrrole-2-carboxylic acid benzyl ester are joined in dimmers by strong hydrogen bonds. The dimmers are aggregated in chains running along the b axis through C-H...Ï€ intermoleculear interactions.
