I have a question:
when would you avoid recrystallizing a solid?

I know only two cases when recrystallization wouldn't work:
1) low melting solids (but I doubt that my compound is really low melting)
2) highly impure solids (it's not that impure)

any other ideas?

low solution stability.  I work with organometallics and I often have issues with solution stability.

If we have other method than recrystallization to purify compounds we can avoid.
For example,in a matrix if u have both acid and base you can easily purify one of them by simple work up(by knowing its pKa value.
