(Hexafluorosilicato‐κ2F,F′)bis(1,10‐phenanthroline‐κ2N,N′)zinc(II) methanol monosolvate
The title compound, [Zn(SiF6)(C12H8N2)2]·CH3OH, contains a neutral heteroleptic tris‐chelate ZnII complex, viz. [Zn(SiF6)(phen)2] (phen is 1,10‐phenanthroline), exhibiting approximate molecular C 2 point‐group symmetry. The ZnII cation adopts a severely distorted octahedral coordination. As far as can be ascertained, the title complex represents the first structurally characterized example of a ZnII complex bearing a bidentate‐bound hexafluorosilicate ligand. A density functional theory study of the isolated [Zn(SiF6)(phen)2] complex was undertaken to reveal the influence of crystal packing on the molecular structure of the complex. In the crystal structure, the methanol solvent molecule forms a hydrogen bond to one F atom of the hexafluorosilicate ligand. The hydrogen‐bonded assemblies so formed are tightly packed in the crystal, as indicated by a high packing coefficient (74.1%).
