Herein we report a water-induced single-crystal to single-crystal transformation that involves the formation of hetero-bimetallic paddlewheel clusters in coordination polymers. Through this transformation, which involves the cleavage and formation of different coordination bonds, two different Cu( ii )-Zn( ii ) and Cu( ii )-Ni( ii ) paddlewheel units exhibiting a 1 : 1 metal ratio were created. Hetero-bimetallic paddlewheel clusters in coordination polymers are formed through a water-induced single-crystal to single-crystal transformation.
