Tetraaqua‐1κO,2κ3O‐(μ‐2,4‐dinitrophenolato‐1κ2O1,O2:2κO1)(2,4‐dinitrophenolato‐1κ2O1,O2)dilithium(I): a dinuclear lithium(I) complex

Abstract:The title complex, [Li2(C6H3N2O5)2(H2O)4], contains two kinds of Li atoms, viz. five‐coordinated and four‐coordinated. The five‐coordinated Li ion has a tetragonal–pyramidal geometry, with a water molecule in the apical position and four O atoms from two 2,4‐dinitrophenolate (2,4‐DNP) ligands in the basal plane. The four‐coordinated Li ion has a tetrahedral geometry, with three water molecules and one phenolate O atom of a 2,4‐DNP ligand. The Li ions are bridged by a phenolate O atom, giving the complex a dinuclear structure. The crystal packing is stabilized by O—H...O hydrogen‐bonding interactions involving the water molecules and nitro O atoms.
