Popis:	Crystal structures are reported for the following complexes [Fe3O(OOCCMe3)6(py)3]ClO4·0.5py, 1; [Mn3O(OOCCMe3)6(py)3]ClO4·MeCN, 2; [Mn3O(OOCCMe3)6(py)3], 4; [Fe3O(OOCCMe3)6(py)3], 5. Crystal data are as follows: 1, system monoclinic, space group P21/n, a = 11.658(5) A, b = 35.450(5) A, c = 14.084(5) A, β = 100.10(1)°, V = 5730(3) A3, Z = 4; 2, orthorhombic, P212121, a = 18.592(11) A, b = 25.924(11) A, c = 13.290(5) A, V = 6405(3) A3, Z = 4; 4, monoclinic, P21/c, a = 17.941(4) A, b = 14.945(3) A, c = 21.655(4) A, β = 96.50(3)°, V = 5769(2) A3, Z = 4; 5, monoclinic, P21, a = 11.800(3) A, b = 20.238(7) A, c = 12.003(2) A, β = 106.97(2)°, V = 2741.6(13) A3, Z = 2. In 1 and 2, the triangular metal ion clusters are close to equilateral geometry, but the coordination polyhedra of the metal ions are significantly different. Those of the fully oxidized triiron(III) cluster are close to the ideal tetragonal symmetry. Those of the trimanganese(III) cluster show strong Jahn−Teller distortions, the four Mn−carboxylat...
