A novel 9-MC-3 and 15-MC-6 onset stacked metallacrown single-molecule magnet: synthesis and crystal structure.

A novel enneanuclear manganese complex, [Mn(9)O(4)(Mesao)(6)(MeO)(3)(O(2)CMe)(3)(OH)(MeOH)(2)]·2.5DMF [1; Me-saoH(2) = 2-hydroxyphenylethanone oxime], was synthesized. The structure of 1 contains an unusual [Mn(9)O(4)] core with an unprecedented defective "supertetrahedron" topology based on two parallel, onset stacked 9-MC-3 and 15-MC-6 metallacrown subunits. Magnetic studies indicate that 1 behaves as a single-molecule magnet.

Dataset on the mechanical property of graphite after molten FLiNaK salt infiltration.

Presented in this article are mechanical property and microstructural data for fluoride molten salt infiltrated graphite at high temperature. Four infiltration pressures (0 kPa, 450 kPa, 600 kPa, and 1000 kPa) and two kinds of graphite (IG-110 and NG-CT-10) were used during molten salt infiltration. After fluoride molten salt infiltration, compression testing and tension testing were performed at 700 °C to determine compressive strength, tensile strength, softening coefficient, stress-strain curve, and absorbed energy. Utilizing scanning electron microscopy (SEM) applied to fracture fragments, SEM micrographs for the fracture surface of molten salt infiltrated graphite and virgin graphite were determined.
