title: A monoclinic polymorph of N,N'-bis-(2,6-diisopropyl-phen-yl)formamidine.
abstract: A new polymorph of N,N'-bis-(2,6-diisopropyl-phen-yl)formamidine, C(25)H(36)N(2), is reported, which is different from the previously reported ortho-rhom-bic structure. The mol-ecule crystallizes in the E-anti configuration, with tautomeric disorder of the N-bonded H atoms and no clear distinction between imine and amine functionalities. The mol-ecules form hydrogen-bonded dimers with inter-molecular N⋯N distances shorter than those in the ortho-rhom-bic polymorph.
