(Received 22 November 2007; accepted 27 November 2007; online 6 December 2007)

The crystal structure of the title compound, C17H24N2O5, was determined in the course of our studies on the preparation of two families of pseudopeptides, viz. hydrazino- and N-amino- peptides. The most significant inter­action in the crystal structure is a bifurcated inter­molecular N—H⋯O hydrogen bond.

Comment top

As part of our continuing studies on the synthesis and structure of hydrazino- and N-amino-peptides, we have described the crystal structure of N-(tert-Butyloxycarbonylamino)phthalimide (Kauffmann et al., 2004). Here we report the crystal structure of the title compound, N-benzoyl-Nβ, Nα- bis (tert-butoxycarbonyl) hydrazine (Fig. 1).

Although the title compound is not chiral, it crystallizes in the non-centrosymmetric space group P212121. The angle between the amide plane and the mean plane of the imidodicarbonate group is 78.43 (18)°, showing that these two groups are nearly perpendicular. The angle between the best-fit phenyl plane and the amide plane of 27.34 (7)° is similar to that reported for the benzamide group (Fong et al., 1996).

In the crystal structure of the title compound, molecules are linked into infinite chains parallel to a via bifurcated N—H···O hydrogen bonds involving both carbonate of the aminoimidodicarbonate group (Fig. 2). All other intermolecular interactions are due to van der Waals forces.

Experimental top

The title compound was prepared from N-(tert-Butyloxycarbonylamino)phthalimide (Brosse et al., 2003), and was crystallized by slow evaporation of an ethanol solution.

Refinement top

All H atoms were located in difference maps. The C-bonded H atoms were placed at calculated positions and refined using a riding model, with C—H distances of 0.93–0.96 Å. The N-bonded H atom was refined with free positional parameters. The H-atom Uiso parameters were fixed at 1.3Ueq(C) for aromatic C—H groups, at 1.3Ueq(N) for the N—H group and at 1.5Ueq(C) for methyl C—H.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
