Crystal structure of the tetra-hydro-furan disolvate of a 94:6 solid solution of [N2,N6-bis-(di-tert-butyl-phosphan-yl)pyridine-2,6-di-amine]-dibromido-manganese(II) and its monophosphine oxide analogue.
2017
The MnBr2 complex of N2,N6-bis(di-tert-butylphosphanyl)pyridine-2,6-diamine (1·MnBr2) co-crystallizes with 5.69% of the monophosphine oxide analogue (1O·MnBr2) and two tetrahydrofuran (THF) molecules, namely [N2,N6-bis(di-tert-butylphosphanyl)pyridine-2,6-diamine]dibromidomanganese(II)–[bis(di-tert-butylphosphanyl)({6-[(di-tert-butylphosphanyl)amino]pyridin-2-yl}amino)phosphine oxide]dibromidomanganese(II)–tetrahydrofuran (0.94/0.06/2), [MnBr2(C21H41N3P2)]0.94[MnBr2(C21H41N3OP2)]0.06·2C4H8O. The 1·MnBr2 and 1O·MnBr2 complexes are occupationally disordered about general positions. Both complexes feature square-pyramidal coordination of the MnII atoms. They are connected by weak N—H⋯Br hydrogen bonding into chains extending along [001]. The THF molecules are located between the layers formed by these chains. One THF molecule is involved in hydrogen bonding to an amine H atom.
