RESUMEN
In the mononuclear title compound, [Co(III)(C(15)H(12)N(2)O(3))(C(5)H(5)N)(3)]ClO(4), the Co(III) ion is coordinated by three pyridine mol-ecules and one N'-(3-meth-oxy-2-oxidobenzyl-idene)benzohydrazidate Schiff base ligand in an O,N,O'-tridentate manner. The Co(III) ion adopts a distorted CoN(4)O(2) octa-hedral coordination environment.
RESUMEN
In the title complex, [Mn(2)(C(15)H(13)N(2)O(3))(3)]ClO(4)·CH(3)OH, the two Mn(II) ions are bridged by two phenolate O atoms from two ligands, forming an Mn(2)O(2) quadrangle. Each Mn(II) ion has a distorted octa-hedral coordination geometry. One Mn(II) ion is coordinated by two N atoms and four O atoms from two ligands, and the other is coordinated by one N atom and five O atoms from three ligands. A dimer is formed by inter-molecular N-Hâ¯O hydrogen bonds. The dimers, perchlorate anions and methanol solvent mol-ecules are further connected into a chain along [01] through N-Hâ¯O and O-Hâ¯O hydrogen bonds.
RESUMEN
In the title mononuclear iron(III) complex, [Fe(C(15)H(13)N(2)O(3))(2)]Cl·H(2)O, the Fe(III) atom has a distorted octa-hedral geometry and is six-coordinated by four O atoms and two N atoms from two ligands. In the crystal structure, the complex cations, Cl(-) anions and water mol-ecules are connected into a chain along [100] through N-Hâ¯O, O-Hâ¯Cl and N-Hâ¯Cl hydrogen bonds. Two adjacent chains are linked by O-Hâ¯O hydrogen bonds.
RESUMEN
A novel dodecanuclear wheel with ten Dy(III) ions and two Co(II) ions bridged by four Schiff-base ligands and sixteen acetates represents the highest-nuclearity 3d-4f example of its type displaying single-molecule magnet behaviour.
