The title compound, [Mn(C12H15NO5)2]·0.39H2O, is a 0.39 hydrate of the isostructural complex bis(2-{[1,1-bis(hydroxymethyl)-2-oxidoethyl]iminomethyl}-6-methoxyphenolato)manganese(IV) that has previously been reported by Back, Oliveira, Canabarro & Iglesias [Z. Anorg. Allg. Chem.(2015),641, 941–947], based on room-temperature data. The current structure that was determined at 100 K reveals a lengthening of theccell parameter compared with the published one due to the incorporation of the partial occupancy water molecule. The title compound crystallizes in the tetragonal chiral space groupP41212; the neutral [MnIV(C12H15NO5)2] molecule is situated on a crystallographicC2axis. The overall geometry about the central manganese ion is octahedral with an N2O4core; each ligand acts as a meridional ONO donor. The coordination environment of MnIVat 100 K displays a difference in one of the two Mn–O bond lengths, compared with the room-temperature structure. In the crystal, the neutral molecules are stacked in a helical fashion along thec-axis direction.

Different Types

Research of hydrogen diffusion in VT6 alloy is carried out considering different types of heat treating and hydrogen charging. The influence of microalloying on the susceptibility to hydride formation and embrittlement of titanium alloys is analyzed, and also effects of an oxide film on hydrogen charging during heat treatment without protective atmosphere, are studied.
