Bead- like precipitation of 5- Aminotetrazole

Finally got around to doing the 5 ATZ synth. My precipitate is forming in solid round bead like formations. Anything I should be worried about or is it all chill?

I thought this would indicate the presence of a contaminant like a co precipitate or dust or something.

A little late to the party... It looks awfully green. It should be yellow. Nitrous acid contamination? As for the bead precipitation not sure. It should crystallise in small rectangular plates. What was your synthesis and purity of the reagents? This post would be more at home in the 5-ATZ thread. Did you attempt to recrystallise it?
