Crystal structure of a Cu(II) complex with a bridging ligand: poly[[penta-kis-[μ2-1,1'-(butane-1,4-di-yl)bis-(1H-imidazole)-κ(2) N (3):N (3')]dicopper(II)] tetranitrate tetra-hydrate].

Bottom Line: The Cu(II) cations are linked by biim ligands to give a 4(4) layer; the layers are further bridged by biim ligands, generating a double sheet with a thickness of 14.61 Å.The sheet features rhombic Cu4(biim)4 windows built up from four Cu(II) centers and four biim ligands with dimensions of 14.11 × 14.07 Å(2).Each window of a layer is penetrated directly by the biim ligand of the adjacent net, giving a two-dimensional→three-dimensional entangled framework.

ABSTRACT
A novel two-dimensional→three-dimensional Cu(II) coordination polymer, {[Cu2(C10H14N4)5](NO3)4·4H2O} n , based on the 1,1'-(butane-1,4-di-yl)bis-(1H-imidazole) (biim) ligand and containing one crystallographically unique Cu(II) atom, has been synthesized under hydro-thermal conditions. The Cu(II) atom is coordinated by five N atoms from biim ligands, one of which has crystallographically imposed inversion symmetry, giving rise to a slightly distorted CuN5 square-pyramidal geometry. The Cu(II) cations are linked by biim ligands to give a 4(4) layer; the layers are further bridged by biim ligands, generating a double sheet with a thickness of 14.61 Å. The sheet features rhombic Cu4(biim)4 windows built up from four Cu(II) centers and four biim ligands with dimensions of 14.11 × 14.07 Å(2). Each window of a layer is penetrated directly by the biim ligand of the adjacent net, giving a two-dimensional→three-dimensional entangled framework.

Mentions: The structure of compound, (I) (Fig. 1 ▶), contains one CuII, two and one half biim ligands, two nitrate ions and two water mol­ecules per asymmetric unit. The CuII cation is five-coordinated and exhibits a distorted CuN5 square-pyramidal coordination geometry from the biim ligands (Table 1 ▶). The cis basal N—Cu—N bond angles range from 88.42 (15) to 90.72 (15)°, and the apical bond angles from 92.02 (14) to 101.23 (15)°.
