Diverse investigations into the synthesis, formation, reactivity and stability of
disulfur dinitride, S2N2, enabled through the fabrication of custom-made
apparatus and tailored reaction conditions, are reported. The polymerisation
process of the former to the (super)conductive polythiazyl material has also
been explored by means of both single crystal X-ray diffraction and in situ
A Doctoral Thesis. Submitted in partial fulfilment of the requirements for the award of Doctor of Philosophy of Loughborough University.
