t-3-Ethyl-r-2,c-7-bis­(4-methoxy­phen­yl)-1,4-diazepan-5-one

The title compound, C(21)H(26)N(2)O(3), crystallizes with two independent mol­ecules in the asymmetric unit. In both independent mol­ecules, the diazepine ring adopts a chair conformation. In the crystal, the independent mol­ecules exist as N—H⋯O hydrogen-bonded R (2) (2)(8) dimers which are linked...

description The title compound, C(21)H(26)N(2)O(3), crystallizes with two independent mol­ecules in the asymmetric unit. In both independent mol­ecules, the diazepine ring adopts a chair conformation. In the crystal, the independent mol­ecules exist as N—H⋯O hydrogen-bonded R (2) (2)(8) dimers which are linked via N—H⋯O hydrogen bonds, forming tetra­mers. The tetra­mers are linked by C—H⋯O hydrogen bonds. In one of the molecules in the asymmetric unit, the terminal C atom of the ethyl group is disordered over two positions with refined occupancies of 0.742 (4) and 0.258 (4).
