摘要：

Experimental and theoretical studies indicate that achieving the maximum possible ground spin state of S-T = 83/2 for the mixed valent Mn-19 coordination cluster is insensitive to replacement of its eight mu(3)-N-3 ligands by mu(3)-Cl, mu(3)-Br, mu(3)-OH or mu(3)-OMe, substantiating that the ferromagnetic interactions are indeed mediated mainly by the internal (mu(4)-O) ligands. The robustness of the inorganic {Mn-III Mn-12(II) 7(mu(4)-O)(8)} core is clear from the molecular structure and ESI-MS studies have shown that the structure of the Mn-19 aggregate, and also of its Mn18Y analogue, are stable beyond the solid state.
