Comment top

Hydroxamic acid derivatives have received considerable attention in recent years as the result of the discovery of their role in the biochemical toxicology of many drugs and other chemicals. Thus, these compounds continue to attract much attention as potential biological agents. The title molecule, C22H18N2O5, contains three branched chains with its centre placed at midpoint of the N. The phenyl ring C1—C6 makes a dihedral angle of 81.85 (8)° with the phenyl ring C10—C15 of benzoyl group, and 12.08 (8)° with the penyl ring C16—C21.

Experimental top

The title compound, C22H18N2O5 was prepared according to the method described by Ayyangark et al. (1986). Crystals of (I) suitable for single-crystal X-ray analysis were grown by slow evaporation of a solution in dichloromethane-methanol (1:3 v/v).

Refinement top

The methyl hydrogen atoms were positioned geometrically (AFIX 137) and refined using a riding/rotating model, with Uiso = 1.5 times Ueq(C). Other H-atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H=0.95 Å and Uiso = 1.2 times Ueq(C).

Special details top

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
