The 22‐membered macrocycle, spanning four endocyclic pyrazole groups, viz. 1,4,9,14,17,22,27,28,29,30‐decaaza‐5,13,18,26‐tetramethylpentacyclo[24.2.1.1 4,7 .1 11,14 .1 17,20 ]triacontane‐5,7(28),11(29),12,18,20(30),24(27),25‐octaene ( 22Pz ), rendered the tetranuclear compound [Cu 4 (22Pz) 2 (CO 3 ) 2 (MeOH) 2 ](ClO 4 ) 4 (MeOH) 4 . The copper(II) ions are in distorted octahedral N 3 O 3 environments. All four pyrazole groups of each macrocycle participate in the coordination of the copper(II) ions. The cationic part of this compound is in fact a dimer of two macrocyclic ligands, each containing two copper(II) ions bridged by two carbonate ions in the highly unusual pentacoordinating fashion.
