Strange green and gold coloured chemical
I worked for a time with squaraine dyes that were often greenish in the crystalline state, but ink-blue when in solution.



However, I would suggest that you take an analytical approach to identifying this compound.  Have you done any NMR, IR or even UV/Vis spectroscopy?  Elemental analysis?

These would be a much safer way to go about identifying the mystery compound.

Good luck, and I'd love to know what you discover!
