Synthesis, Characterization, and Magnetic Property of a Novel Dimer-of-Di(<i>μ</i>-oxo)dimanganese-Dimers with Two Coordinated Water Molecules in (III,IV,III,IV) Oxidation State
di(μ-oxo)manganese(III)manganese(IV) dimers which are linked by two tmdps and hydrogen bonding network between two coordinated water molecules and two alkoxo groups to form a dimer-of-dimers with a bilayered structure with dimer-dimer separation of 5.9 A. The Mn–Mn separations are 2.644(2)—2.651(2) A. Magnetism of 1 was well interpreted in terms of the model based on two kinds of the exchange interactions

Dinuclear Cobalt(II) Complexes Containing 1,3-(or 1,5-)Bis[bis(2-pyridylmethyl)amino]-2-propanolato (or -3-pentanolato): Preparation and Reaction with Molecular Oxygen
Two dinuclear cobalt(II,II) complexes, [Co2(tpdp)(CH3COO)](ClO4)2·0.5H2O (1) and [Co2(tmdp)(CH3COO)](ClO4)2·H2O (2), were prepared, where Htpdp and Htmdp are 1,3-bis[bis(2-pyridylmethyl)amino]-2-propanol and 1,5-bis[bis(2-pyridylmethyl)amino]-3-pentanol respectively. Their electronic spectral and magnetic data revealed that 1 and 2 are five-coordinate in the high-spin state, in the same manner as
