Crystal structure of bromido-penta-kis-(tetra-hydro-furan-?O)magnesium bis-[1,2-bis-(di-phenyl-phosphan-yl)benzene-?2 P,P']cobaltate(-1) tetra-hydro-furan disolvate.


ABSTRACT: Structural characterization of the ionic title complex, [MgBr(THF)5][Co(dpbz)2]·2THF [THF is tetra-hydro-furan, C4H8O; dpbz is 1,2-bis-(di-phenyl-phosphan-yl)benzene, C30H24P2], revealed a well-separated cation and anion co-crystallized with two THF solvent mol-ecules that inter-act with the cation via weak C-H?O contacts. The geometry about the cobalt center is pseudo-tetra-hedral, as is expected for a d 10 metal center, only deviating from an ideal tetra-hedral geometry because of the restrictive bite angles of the bidentate phosphane ligands. Three THF ligands of the cation and one co-crystallized THF solvent mol-ecule are each disordered over two orientations. In the extended structure, the cations and THF solvent mol-ecules are arranged in (100) sheets that alternate with layers of anions, the latter of which show various ?-inter-actions, which may explain the particular packing arrangement.
