“…A search in the Cambridge Crystallographic Database (Groom et al, 2016) for the fragment 1,3-bis[(benzylidene)amino]propan-2-ol yielded the following structures: N,N 0 -[(2-hydroxy-1,3-propanediyl)bis(nitrilomethylylidene-2,1-phenylene)]bis(4-methylbenzenesulfonamide) (Popov et al, 2009), 2,2 0 -[(2-hydroxypropane-1,3-diyl)bis(nitrilomethylylidene)]diphenol (Azam, Hussain et al, 2012), 1,3-bis(2-hydroxy-5-bromosalicylideneamine)propan-2-ol (Elmali, 2000), 1,3-bis[(E)-(2-chlorobenzylidene)amino]propan-2-ol and 1,3-bis[(4-methoxybenzylidene)amino]propan-2-ol (Rivera et al 2016b). In each of these structures, the N C double bonds adopt E conformations.…”
