Compound was further studied in a water / acetonitrile mixtures of various component ratios. It was found that solutions with moderate water content (above 40 Vol.%) are unstable and aggregate with formation of non-absorbing solutions with pink precipitate with green gloss over a course of 5 hours to overnight. Unexpectedly, small rod-or needle-like particles obtained from longer precipitation time have no far order (x-ray diffraction examination for these structures failed in multiple attempts with various setups).
