Crystal structure of benzhydrazide, NH₂NHCO(C₆H₅)

Quantitative Gas-Solid Reactions with ClCN and BrCN: Synthesis of Cyanamides, Cyanates, Thiocyanates, and Their Derivatives

“…The horizontal edges of these basins are parallel to the long crystal axis of 12 a (Figure 5 d). The correlation with the crystal structure is striking: the packing [27] of 12 a on (100) is shown in Figure 6 (see p. 2473). The molecules are inclined at an angle of 718 on that face in four orientations and form double layers.…”

“…Figure 6. Stereoscopic view of the crystal packing of 12 a (P2 1 /c) [27] onto the (100)-face showing one double layer with the 3 D network of hydrogen bonds (dashed) between the functional groups. These groups are shielded by the phenyl groups which penetrate the face at angles of 718 in two directions; the (001)-face lies on the top of the model, while (010) is to the right.…”

4-Iodobenzohydrazide

“…For related structures, see: Kallel et al (1992); Saraogi et al (2002); Ashiq, Jamal et al (2008). For related literature, see: Ara et al (2007); Ashiq, Ara et al (2008); Bernstein et al (1994).…”

Four substituted benzohydrazides: hydrogen-bonded structures in one, two and three dimensions

“…Even the two hydrogen bonds listed in the original report (Saraogi et al, 2002) suf®ce to generate this type of (100) sheet. For the unsubstituted compound (VI), there is again only a very brief report with no discussion of the supramolecular aggregation (Kallel et al, 1992). Again, reexamination of the structure using coordinates as retrieved from the Cambridge Structural Database (Allen, 2002;refcode VOPJEP) shows that this compound forms exactly the same type of (100) sheet as the 4-chloro analogue (V), and that it is, indeed, isomorphous and effectively isostructural with compound (V), although this fact was not noted in the report on (V) (Saraogi et al, 2002).…”
