TL;DR: In this paper, the electrochemical and magnetochemical properties of [Mn 12 O 12 (O 2 CPh) 16 (H 2 O) 4 ] (3), its solvate 3.
Abstract: The syntheses and electrochemical and magnetochemical properties of [Mn 12 O 12 (O 2 CPh) 16 (H 2 O) 4 ] (3), its solvate 3.PhCOOH-CH 2 Cl 2 , and [Mn 12 O 12 (O 2 CMe) 16 (H 2 O) 4 ].MeCOOH-3H 2 O (4) are reported. Complex 3 can be prepared either by reaction of Mn(OAc) 2 .4H 4 O, benzoic acid, and NBu n 4 MnO 4 in pyridine or by reaction of PhCOOH with complex 4 slurried in CH 2 Cl 2 .

TL;DR: In this paper, it has been shown that the Mo=Mo bond in M02(OR)6 compounds is labile toward a number of oxidative-addition reactions, including those involving molecular oxygen.
Abstract: : It has previously been shown that the Mo=Mo bond in M02(OR)6 compounds is labile toward a number of oxidative-addition reactions. Treatment with halogens leads to the formation of Mo2(OR)6X4 (M-M) compounds (R = i-Pr, X = C1, Br and I), and addition of ROOR to formation of Mo2(OR)8 (R = i-Pr). Reaction with benzoyl peroxide gave a compound Mo2(OR)6(02CPh)2 (R = i-Pr), believed to contain a Mo-Mo bond. These earlier findings prompted us to continue to investigate oxidative-additions with simple X2 molecules. Reported here are studies involving molecular oxygen.

TL;DR: In this article, it was shown that the magnetization of the Mn12 cluster is highly anisotropic and the magnetisation relaxation time becomes very long below a temperature of 4 K, giving rise to pronounced hysteresis.
Abstract: MAGNETIC materials of mesoscopic dimensions (a few to many thousands of atoms) may exhibit novel and useful properties such as giant magnetostriction, magnetoresistivity and magnetocaloric effects1–4. Such materials also allow one to study the transition from molecular to bulk-like magnetic behaviour. One approach for preparing mesoscopic magnetic materials is to fragment bulk ferromagnets; a more controllable method is to take a 'bottom-up' approach, using chemistry to grow well defined clusters of metal ions5,6. Lis7 has described a twelve-ion manganese cluster in which eight of the Mn ions are in the +3 oxidation state (spin S=2) and four are in the +4 state (S=3/2). These ions are magnetically coupled to give an S=10 ground state8, giving rise to unusual magnetic relaxation properties8,9. Here we report that the magnetization of the Mn12 cluster is highly anisotropic and that the magnetization relaxation time becomes very long below a temperature of 4 K, giving rise to pronounced hysteresis. This behaviour is not, however, strictly analogous to that of a bulk ferromagnet, in which magnetization hysteresis results from the motion of domain walls. In principle, a bistable magnetic unit of this sort could act as a data storage device.

TL;DR: Double-decker phthalocyanine complexes with Tb3+ or Dy3+ showed slow magnetization relaxation as a single-molecular property and a significant temperature rise results from a mechanism in the relaxation process different from that in the transition-metal-cluster SMMs.
Abstract: Double-decker phthalocyanine complexes with Tb3+ or Dy3+ showed slow magnetization relaxation as a single-molecular property. The temperature ranges in which the behavior was observed were far higher than that of the transition-metal-cluster single-molecule magnets (SMMs). The significant temperature rise results from a mechanism in the relaxation process different from that in the transition-metal-cluster SMMs. The effective energy barrier for reversal of the magnetic moment is determined by the ligand field around a lanthanide ion, which gives the lowest degenerate substate a large |Jz| value and large energy separations from the rest of the substates in the ground-state multiplets.
