Description

Inorganic compound, complex compound transitional metal bismuth, organic compound thiourea and inorganic nitric acid. From water solutions crystallizes as monohydrate.

Precursors

Reaction between bismuth(III) nitrate and thiourea

Chemical equation:

Bi(NO3)3 + 5CS(NH2)2 = [Bi(NO3)(CS(NH2)2)5](NO3)2

For preparation of 100.00g of nitratopentakis-tiokarbamatbismuth(III) nitrate monohydrate а 61.12g of bismuth(III) nitrate pentahydrate and 47.96g of thiourea is required.
Add to the flask with thiourea solution a bismuth(III) nitrate solution with stirring. After reaction will stop, filter the solution and use it for crystal growing.

Notes

The solution is hydrolyzed with hydrogen sulphide emission after few weeks.

Storage conditions

Store in its original form or under several layers of varnish at average humidity and room temperature. Do not store in matchboxes or cotton wool and do not heat.

Solubility

Soluble in water.
