Properties: White cryst powder or cubic crystals (zinc-blende structure); stable to air and light if dry, but in presence of moisture turns green on exposure to air and blue to brown on exposure to light. mp 430°; d425 4.14. Sparingly sol in water with partial decompn; practically insol in alcohol, acetone; sol in concd HCl, concd NH4OH with formation of complexes. Solns oxidize rapidly in air. Keep tightly closed and protected from light.
