We are proud to announce that our latest manuscript was accepted by Journal of Molecular Structure. The paper reveals the crystal structure of a new anhydrous solid-state form of Azathioprine, determined directly form powder X-Ray diffraction data, employing the direct-space genetic algorithm technique for structure solution, followed by Rietveld refinement, and you can read it here: https://www.sciencedirect.com/science/article/abs/pii/S0022286018312602.
