| Abstract: | The crystal structure of the title complex, Cu(C7H8N4)2(H2O)2](ClO4)2, consists of a discrete centrosymmetric Cu(C7H8N4)2(H2O)2]2+ cation and two perchlorate anions. The CuII centre is six‐coordinated by four N donors from the two pyrazole rings Cu—N 1.998 (2) and 2.032 (3) Å] and two O atoms from the water molecules occupying the apical sites Cu—O 2.459 (3) Å]. The coordination geometry of the complex can be described as octahedral. There is a unique three‐dimensional network in which the perchlorate units are linked by a combination of strong O—H?O and weak C—H?O hydrogen bonds. |
