| Popis: | 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. |
