The title compound, Mn(CHOP)(CHOH)·3CHOH, was formed in the reaction between a hydrate of a manganese(II) salt [either Mn(NO)(HO) or MnCl(HO)] with a methanol solvate of lithium bis-(2,6-diiso-propyl-phen-yl) phosphate, {Li[OOP(O-2,6- PrCH)]·(CHO)}·CHO, in methanol. The structure has monoclinic () symmetry at 150 K. The complex consists of an [Mn{OOP(O-2,6- PrCH)}(CHOH)] cation, an [OOP(O-2,6- PrCH)] anion and three non-coordinating methanol mol-ecules. The anion demonstrates disorder of an isopropyl group [occupancy ratio is 0.57 (4):0.43 (4)]. The di-aryl-phosphate ligand in the cation exhibits a κ terminal coordination mode. The Mn atom is in a nearly unperturbed octa-hedral environment. The [Mn{OOP(O-2,6- PrCH)}(CHOH)] cation exhibits one intra-molecular O-H⋯O bond, and is coordinated two inter-molecular O-H⋯O hydrogen bonds to the [OOP(O-2,6- PrCH)] anion. The cations, anions and non-coordinating methanol mol-ecules are linked into infinite chains along the -axis direction 0-H⋯O hydrogen bonding. The complex is of inter-est as a possible inhibitor for the thermal decomposition of polydi-methyl-siloxane. The crystal studied was refined as an inversion twin with a domain ratio of 0.47 (3):0.53 (3).
