| Abstract: | The organic ligand (1-methyl-1H-benzo[d]imidazol-2-yl)methanol (HL1) was used to react with Cu(ClO4)2·6H2O and triethylamine at 80°C to afford the complex [Cu4(L1)6]·(ClO4)2·CH3CN ( 1 ). Every four-coordinated Cu(II) ion is surrounded with NO3 coordinated environment, and every five-coordinated Cu(II) ion is surrounded with N2O3 coordinated environment. Changing the metal salt to Zn(NO3)2·6H2O, and after adding CH3COONa, afforded the complex [Zn4(L1)4(NO3)2(CH3COO)2] ( 2 ), in which every five-coordinated Zn(II) ion is surrounded with NO4 coordinated environment. High-resolution electrospray ionization mass spectrometry results revealed that complex 1 broke into the most stable fragment [Cu2(L1)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. |
