Abstract

It is shown that enantiomorph structures of a noncentrosymmetric crystal can be determined, in the absence of anomalous diffraction signals, by measuring two series of reference-beam oscillation diffraction patterns related by an inverse-beam geometry. The corresponding intensities of the Friedel pairs recorded on the two sets of images exhibit the characteristic three-beam interference effects that provide the unambiguous phase information. The experimental arrangement and the data-analysis procedure are demonstrated through an experimental example on tetragonal lysozyme.

Coordination-driven self-assembly: solids with bidirectional porosity.

Coordination-driven self-assembly reactions have been used in the preparation of a variety of discrete supramolecular species, some of which have shown promise as synthetic receptors. Many highly ordered coordination polymers and porous networks have been prepared in a similar fashion. While a few of these solids are capable of the uptake of small organic molecules in the resultant molecular channels, the formation of truly porous structures has frequently been thwarted by lattice interpenetration. A strategy for the formation of porous solids that may circumvent this problem is based on the covalent construction of nanoscale macrocycles which, when eclipsed in the solid state, may lead to porous, tubular assemblies. We have incorporated these concepts toward the realization of a bidirectionally porous solid. The metal-directed, self-assembly of a conjugated, macrocyclic ligand provides a discrete, supramolecular entity in solution and the solid state. X-ray crystallographic analysis establishes that this assembly packs such that bidirectional channels are realized, and the incorporation of only ClCH2CH2Cl into the crystal lattice demonstrates that these channels are potentially suitable for the selective uptake of small organic guests.

Exceptional kinetic propensity of hydroxymethyl phosphanes toward Rh(III) stabilization in water.

The reactions of (HOCH2)2P(C6H4)P(CH2OH)2 (HMPB) and P(CH2OH)3 (THP) with RhCl3.xH2O in aqueous media gave water-soluble complexes cis-[RhCl2{eta2-(HOCH2)2P(C6H4)P(CH2OH)2}2]Cl (3) and fac-[RhCl3(P(CH2OH)3)3] (4) respectively in good yields, X-ray crystal structures of 3 and 4 confirmed their molecular constitution. These reactions provide the first examples demonstrating the kinetic propensity of hydroxymethyl phosphanes to stabilize Rh in +3 oxidation state in water.

Structures of human oxy- and deoxyhaemoglobin at different levels of humidity: variability in the T state.

High-salt crystals of human oxy- and deoxyhaemoglobin have been studied at different levels of environmental humidity and solvent content. The structure of the oxy form remains relatively unchanged at all levels. The deoxy form, however, undergoes a water-mediated transformation when the relative humidity around the crystals is reduced below 93%. The space group is maintained during the transformation, but the unit-cell volume nearly doubles, with two tetrameric molecules in the asymmetric unit of the low-humidity form compared with one in the native crystals. Interestingly, the haem geometry in the low-humidity form is closer to that in the oxy form than to that in the native deoxy form. The quaternary structure of one of the tetramers moves slightly towards that in the oxy form, while that in the other is more different from the oxy form than that in the high-salt native deoxy form. Thus, it would appear that, as in the case of the liganded form, the deoxy form of haemoglobin can also access an ensemble of related T states.
