First Structure Published Using Rigaku SCXmini™ Benchtop Small Molecule Diffraction System

First Structure Published Using the Rigaku SCXmini™ Benchtop Small Molecule Diffraction System

The Woodlands, TX — March 17, 2006. Rigaku today announced the first publication of a X-ray crystal structure employing the new Rigaku SCXmini benchtop single crystal diffraction system. The structure of bis(2-amino-3-hydroxy-1-phenylpropanolato-κ2N,O1) (ethylenediamine-κ2N,N') cobalt(III) iodide  monohydrate [Co(C9H12NO2)2(C2H8N2)]I · H2O, was published in the latest issue of Acta Crystallographica Section E, Volume 62, Part 4, pages m696-698. Originally synthesized and crystallized in about 1978, its structure was published the following year as part of a synthetic and spectroscopic project. The structure was redetermined in order to resolve some disorder in the earlier determination.

The Rigaku SCXmini represents a new paradigm in small molecule crystallography: affordable, reliable, easy-to-use, low cost-of-ownership access for routine automated structure determination. Specifically engineered by the world's leading analytical X-ray instrumentation vendor to provide colleges, universities, and industry with access to definitive molecular structure determination, the Rigaku SCXmini system allows single crystal diffraction to become a routine laboratory method and teaching tool in the same way that NMR and FT-IR did more than a decade ago.

In addition to routine structure determination by non-crystallographers in industry, the Rigaku SCXmini was developed to address two clear-cut needs within the higher education environment. First was to offer an affordable, low maintenance, low cost-of-ownership crystallography system for teaching. The Rigaku SCXmini was designed for undergraduate labs at major universities as well as for science departments at predominantly undergraduate institutions. Second, it fulfills the need within research departments to expand X-ray structure determination capability beyond the realm of professional crystallographers. Inorganic and organometallic graduate students as well as postdocs can now obtain publication-quality definitive structures on an instrument that they can easily operate themselves.

This newest member of Rigaku's small molecule line of integrated solutions was designed to offer outstanding performance, in a small package and at a fraction of the price and cost-of-ownership of a conventional single crystal XRD system. It features the combination of the new advanced Mercury 2 CCD detector with a simplified goniometer, a sealed-tube X-ray source, and automated software to makes the Rigaku SCXmini perfect for either routine structure determination by non-crystallographer researchers or as a teaching tool.
