【 摘 要 】

The title compound, [Mn(C24H34O4P)(CH3OH)5](C24H34O4P)·3CH3OH, was formed in the reaction between a hydrate of a manganese(II) salt [either Mn(NO3)2(H2O)6 or MnCl2(H2O)4] with a methanol solvate of lithium bis­(2,6-diiso­propyl­phen­yl) phosphate, {Li[OOP(O-2,6-iPr2C6H3)2]·(CH4O)3}·CH4O, in methanol. The structure has monoclinic (Cc) symmetry at 150 K. The complex consists of an [Mn{OOP(O-2,6-iPr2C6H3)2}(CH3OH)5]+ cation, an [OOP(O-2,6-iPr2C6H3)2]− anion and three non-coordinating methanol mol­ecules. The anion demonstrates disorder of an isopropyl group [occupancy ratio is0.57 (4):0.43 (4)]. The di­aryl­phosphate ligand in the cation exhibits a κ1O terminal coordination mode. The Mn atom is in a nearly unperturbed octa­hedral environment. The [Mn{OOP(O-2,6-iPr2C6H3)2}(CH3OH)5]+ cation exhibits one intra­molecular O—H⋯O bond, and is coordinated via two inter­molecular O—H⋯O hydrogen bonds to the [OOP(O-2,6-iPr2C6H3)2]− anion. The cations, anions and non-coordinating methanol mol­ecules are linked into infinite chains along the c-axis direction via 0—H⋯O hydrogen bonding. The complex is of inter­est as a possible inhibitor for the thermal decomposition of polydi­methyl­siloxane. The crystal studied was refined as an inversion twin with a domain ratio of 0.47 (3):0.53 (3).
