چکیده
The title compound, C(13)H(19)NO, exhibits a non-planar structure in which the 2,6-diisopropyl-phenyl ring is tilted at a dihedral angle of 77.4 (1)° with respect to the formamide group. This is the largest dihedral angle known among structurally characterized formamides. The mol-ecules are linked via N-H⋯O hydrogen bonds, forming infinite chains which run along the b-axis directions.

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-mol...

The asymmetric unit of the title compound, C(29)H(34)N(2)O, contains two mol-ecules in which the N-containing six-membered rings assume different conformations viz. half-chair and envelope. Inter-molecular N-H⋯O hydrogen bonding via the amide groups cross-link the mol-ecules in the crystal structure.
