The MAX IV imaging concept.

The MAX IV Laboratory is currently the synchrotron X-ray source with the beam of highest brilliance. Four imaging beamlines are in construction or in the project phase. Their common characteristic will be the high acquisition rates of phase-enhanced images.

The macromolecular crystallography beamline I911-3 at the MAX IV laboratory.

The macromolecular crystallography beamline I911-3, part of the Cassiopeia/I911 suite of beamlines, is based on a superconducting wiggler at the MAX II ring of the MAX IV Laboratory in Lund, Sweden. The beamline is energy-tunable within a range between 6 and 18 keV. I911-3 opened for users in 2005.

Design and synthesis of a C2-symmetric self-complementary hydrogen-bonding cleft molecule based on the bicyclo[3.3.1]nonane and 4-oxo-5-azaindole framework. formation of channels and inclusion complexes in the solid state.

The synthesis of a C2-symmetric cleft molecule 2 based on the fused framework between bicyclo[3.3.1]nonane and 4-oxo-5-azaindole, incorporating a self-complementary hydrogen-bonding motif, in both racemic and enantiomerically pure forms is reported.

What kinds of three-dimensional nets are possible with tris-chelated metal complexes as building blocks?

Tris-chelated metal complexes with octahedral geometry are sometimes used as building blocks for "self assembly" and "crystal engineering". These versatile building blocks easily form honey-comb type 2D nets. However, in this Perspective we discuss the different types of 3D nets that can be formed with these starting materials using Wells classification, and concentrate on the (10,3) nets.

Methyl 2,6-di-O-benzyl-3,4-O-phenylphosphinediyl-beta-D-galactopyranoside(P-B)borane with chirality on the P atom.

A carbohydrate-derived optically active P-chiral dioxophenylphospholane-borane complex, C(27)H(32)BO(6)P, was prepared from bis(diethylamino)phenylphosphine and methyl 2,6-di-O-benzyl-beta-D-galactopyranoside. The phosphinite was prepared with high diastereoselectivity and in good yield. The absolute configuration (R) at the P atom was deduced from the known configuration of the sugar moiety.
