The organic ligand (1‐methyl‐1 H ‐benzo[ d ]imidazol‐2‐yl)methanol (HL 1 ) was used to react with Cu(ClO 4 ) 2 ·6H 2 O and triethylamine at 80°C to afford the complex [Cu 4 (L 1 ) 6 ]·(ClO 4 ) 2 ·CH 3 CN ( 1 ). Every four‐coordinated Cu(II) ion is surrounded with NO 3 coordinated environment, and every five‐coordinated Cu(II) ion is surrounded with N 2 O 3 coordinated environment. Changing the metal salt to Zn(NO 3 ) 2 ·6H 2 O, and after adding CH 3 COONa, afforded the complex [Zn 4 (L 1 ) 4 (NO 3 ) 2 (CH 3 COO) 2 ] ( 2 ), in which every five‐coordinated Zn(II) ion is surrounded with NO 4 coordinated environment. High‐resolution electrospray ionization mass spectrometry results revealed that complex 1 broke into the most stable fragment [Cu 2 (L 1 ) 3 ] + , and it also can assemble high nuclear peaks in solution. For complex 2 , it was found that the complex exhibited different component distribution in solution. Not only were there substitutions between coordinated anions, but the high nuclear peaks could also be detected.
