Dominant Feature

The title complex, [Li2Ni(C11H21N3Si2)2(C4H8O)2], is a trimetallic complex of two LiIcations and a NiIIcation bridged by twoN,N′-(pyridine-2,6-diyl)bis(trimethylsilylamide) ligands that crystallizes in theFdd2 space group. The molecule hasC2rotational symmetry, with the NiIIcation located on the twofold axis. The coordination sphere of the NiIIcation is composed of two amido N and two pyridyl N-atom donors in a distorted square-planar geometry. The LiIcations 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.
