Figure 7.2 Synthesis of coordination polymers by a grinding-annealing technique: (a) dry grinding of copper( II ) acetate monohydrate with

HCNacac produces a hydrated monomeric complex Cu(H 2 O)(CNacac) 2 that, upon heating to 100 1C in the solid state, loses
water to form a coordination polymer of composition Cu(CNacac) 2 ; (b) grinding of 4,4 0 -bipyridinium dihydrochloride with zinc
chloride yields the salt 4,4 0 -dipyridinium tetrachlorozincate. Heating of the solid salt leads to a loss of HCl and the formation
of the coordination polymer Zn(bipy)Cl 2 .
