Bis[μ-N,N′-(pyridine-2,6-di­yl)bis­(tri­methyl­silyl­amido)-1κ2N1,N2;2:3κ2N6:N6]bis­(tetra­hydro­furan)-2:3κ2O-1-nickel(II)-2,3-lithium(I)

The title complex, [Li2Ni(C11H21N3Si2)2(C4H8O)2], is a trimetallic complex of two LiI cations and a NiII cation bridged by two N,N′-(pyridine-2,6-di­yl)bis(tri­methyl­silyl­amide) ligands that crystallizes in the Fdd2 space group. The mol­ecule has C2 rotational symmetry, with the NiII cation located on the twofold axis. The coordination sphere of the NiII cation is composed of two amido N and two pyridyl N-atom donors in a distorted square-planar geometry. The LiI cations are coordinated by two amido N-atom donors and a tetra­hydro­furan mol­ecule with a long inter­action with a pyridyl N-atom donor. The coordinating tetra­hydro­furan ligand and a tri­methyl­silyl group are disordered. Intra- or inter­molecular hydrogen bonding, as well as π–π stacking, are not observed between the mol­ecules, likely indicating that weak electrostatic inter­actions are the dominant feature leading to the crystal structure.
