Versuchsvorschrift

A bluish white powder of copper oxalate was mixed with an excessive amount of hydrazine monohydrate (liquid) and the mixture stirred at room temperature, by which both the compounds formed a complex. By so doing, a purple copper oxalate-hydrazine complex (composite compound) was obtained. The composite compound was thought to be a complex formed as a result of coordinate-bonding through unshared electron pairs of nitrogen which constituted hydrazine to copper atoms contained in the copper oxalate.
