Abstract

In the crystal structure of the title compound [systematic name: 5H-dibenzo[a,d]cyclo­hepta­triene-5-carboxamide–meth­anoic acid (1/1)], C16H13NO·CH2O2, the cytenamide and solvent mol­ecules form a hydrogen-bonded R 2 2(8) dimer motif, which is further connected to form a centrosymmetric double-motif arrangement. The asymmetric unit contains two formula units.

Highlights

  • H atoms treated by a mixture of independent and constrained refinement max = 0.58 e Å 3

  • H atoms treated by a mixture of independent and constrained refinement w = 1/[σ2(Fo2) + (0.0728P)2 + 0.6562P]

  • The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
