A data mining study of electronic Kohn-Sham band structures was performed toidentify Dirac materials within the Organic Materials Database (OMDB). Out ofthat, the 3-dimensional organic crystal5,6-bis(trifluoromethyl)-2-methoxy-1$H$-1,3-diazepine was found to hostdifferent Dirac line-nodes within the band structure. From a group theoreticalanalysis, it is possible to distinguish between Dirac line-nodes occurring dueto 2-fold degenerate energy levels protected by the monoclinic crystallinesymmetry and 2-fold degenerate accidental crossings protected by the topologyof the electronic band structure. The obtained results can be generalized toall materials having the space group $P2_1/c$ (No. 14, $C^5_{2h}$) byintroducing three distinct topological classes.
