This experiment will provide the first single crystal neutron diffraction structure of an alkane bound to a metal centre and give insight into the mechanism of the formation of this complex in the solid-state. This would be a study of an alkane complex by single crystal neutron diffraction which has never been reported and follow the mechanism of addition of H2 (or D2) using single crystal diffraction experiments. We have the crystalline material in hand, a reliable synthetic technique and a sample that is well set-up for extended collection times. Neutron data will provided unparalleled insight into the mode of C?H activation of an alkane at a metal centre and will have additional impact in the fields of catalysis and organic synthesis. Given the nature of the research and the imminent long shut-down of ISIS, we are making this application beam-time by the Rapid Access route.
