Nowadays the interest in Cd(II) coordination compounds comes from their diverse applications especially in photochemistry due to their luminescent coordination complexes in the forms of monomeric, multinuclear, and polymeric species. The d10 configuration of the Cd(II) cation allows for coordination geometries from tetrahedral through trigonal-bipyramidal and square-pyramidal to octahedral ones. Being soft and borderline acids according to Pearson classification [1], Cd(II) cations are able to coordinate simultaneously in solution to both hard oxygen-containing and soft nitrogen-containing organic bases. We used the 1,2cyclohexanedionedioxime (NioxH2) and cadmium formate for the fabrication of 0D coordination monomer Cd(NioxH2)2(HCOO)2 (1). Adding the 1,2-bis(4-pyridyl)ethane (bpe) in the same synthetic conditions we obtained a 1D polymer [Cd(HCOO)2(NioxH2)bpe] (2), where the bpe ligand substituted one NioxH2 molecule and placed in the equatorial plane, thus it bears a linker function between two robust bulky Cd(II)-dioxime units. Compound 1 crystallizes in the monoclinic space group Cc with a = 21.529(2), b=8.258(3), c=13.430(1)Å, β =128.011(1)° and Z=4. Compound 2 crystallizes in the triclinic space group P-1 with a=13.849(1), b=13.980(1), c=15.385(1)Å, α= 91.493(6), β=110.928(7), γ= 109.633(7)° and Z=2. The X-ray study of compound 1 (left) shows six-coordinate geometry at the cadmium center. Metal environment consists from four nitrogen atoms of two NioxH 2 molecules and two oxygen atoms of two monodentate formate anions. In the 1D polymer 2 (right) the Cd(II) cation is also hexacoordinated in the N 4O 2environment. Its basal plane is defined by a bidentate NioxH2 molecule and two monodentate formate anions, and the bidentate bpe ligands occupy the apical sites, bpe being coordinated to a symmetryrelated metal atom in a bridge function and provides Cd ... Cd separation of 13.85 Å. Both compounds demonstrate luminescent properties. Acknowledgements: This work was supported by the 10.819.05.03F project 1. D.F. Shriver, P.W.
