Hydrogen Bonded

Procedures are outlined for generation of crystal structures of primary amide molecules by constructing the possible ways in which the molecules may pack. For each given one- or two-dimensional hydrogen-bonded array, ensembles of three-dimensional crystal structures are generated by considering the possible ways in which the arrays may be juxtaposed. Observed and generated hypothetical molecular arrangements are analysed to highlight both favourable and unfavourable features, particularly in terms of close packing principles, the size and shape of the molecule, van der Waals and Coulomb interactions and N-H ∙ ∙ ∙ O bonding geometry.

In the title compound, C10H5ClO3, a chlorinated 3-formylchromone derivative, all atoms are essentially coplanar (r.m.s. deviation = 0.0592 Å for all non-H atoms), with the largest deviation from the least-squares plane [0.1792 (19) Å] being for the chromone-ring carbonyl O atom. In the crystal, molecules are linked through C—H...O hydrogen bonds to form tetrads, which are assembled by stacking interactions [centroid–centroid distance between the pyran rings = 3.823 (3) Å] and van der Waals contacts between the Cl atoms [Cl...Cl = 3.4483 (16) Å and C—Cl...Cl = 171.73 (7)°] into a three-dimensional architecture.

The title compound, [Ag2Mn(CN)4(C10H8N2)]nor Mn(bipy){Ag(CN)2}2(bipy = 2,2′-bipyridine) is isostructural with Cd(bipy){Au(CN)2}2[Guoet al.(2009).CrystEngComm,11, 61–66]. The MnIIatom has crystallographically imposed twofold symmetry and a distorted octahedral coordination sphere consisting of six N atoms from one bipyridine ligand and four dicyanoargentate(I) anions, [Ag(CN)2]−, while the AgIatom of the complex anion displays the expected linear geometry. Each [Ag(CN)2]−unit connects to two neighbouring [Mn(bipy)]2+cations to give an threefold interpenetrating quartz-like three-dimensional framework. No directional interactions beyond van der Waals contacts are observed.

This methodology will be illustrated using two proteins under investigation in our laboratory, the T4 DNA helix destabilizing protein gp32*I and the crotoxin complex crystal.

Evolution Of Microstructure

In all fields of microscopy there is an increasing interest in the quantification of microstructure. This interest may stem from a desire to establish quality control parameters or may have a more fundamental requirement involving the derivation of parameters which partially or completely define the three dimensional nature of the microstructure. This latter categorey of study may arise from an interest in the evolution of microstructure or from a desire to generate detailed property/microstructure relationships. In the more fundamental studies some convolution of two-dimensional data into the third dimension (stereological analysis) will be necessary.In some cases the two-dimensional data may be acquired relatively easily without recourse to automatic data collection and further, it may prove possible to perform the data reduction and analysis relatively easily. In such cases the only recourse to machines may well be in establishing the statistical confidence of the resultant data. Such relatively straightforward studies tend to result from acquiring data on the whole assemblage of features making up the microstructure. In this field data mode, when parameters such as phase volume fraction, mean size etc. are sought, the main case for resorting to automation is in order to perform repetitive analyses since each analysis is relatively easily performed.
