The melting point and boiling point are too high for the compound to be a covalently bonded substance. But generally compounds formed between non-metals and groups 1 & 2 have much higher melting and boiling points than those in your question.

So the compound is most likely a combination of a transition metal and a non-metal which means it would have moderate to low solubility in water  and some electrical conductivity in aqueous solutions.
