Abstract:
Three Cd coordination polymers with 2,3-pyrazinedicarboxylic acid (pzdc) and N-donor ligand, {[Cd(pzdc) (2,2'-bpy)] center dot H2O}(n) (1), {[Cd(pzdc)(2,2'-bpy)] center dot 2H(2)O}(n) (2) and {[Cd(pzdc) (H2O)(2)] center dot 2H(2)O}(n) (3), have been synthesized and characterized. Complex 1 crystallizes in monoclinic, space group P2(l)/c with a=1.082 47(8) nm, b=1.443 01(9) nm, c=1.025 87(7) nm, beta=98.433(3)degrees, V=1.585 10(19) nm(3); complex 2 belongs to monoclinic, space group P2(l)/n. with a=1.171 9(5) nm, b=1.191 8(4) nm, c=1.359 5(6) nm, beta=110.474(17)degrees, V=1.778 9(13) nm(3); complex 3 crystallizes in monoclinic, space group P2(l)/c with a=0.669 54(3) nm, b=0.773 24(3) nm, c=2.070 60(12) nm, beta=93.050 4(16)degrees, V=1.070 46 (9) nm(3). The X-ray diffraction structure analysis indicates that the pzdc ligand in these complexes is coordinated to three Cd atoms through its four donors, forming a (4,8(2)) net 2D network structure in 1 and 2, while obtaining a ID chain and hydrogen bonding 3D structure in 3. Complexes I and 3 both exhibit photoluminescent emissions at 415 nm (lambda(ex)=313 nm). CCDC: 673389, 1; 673390, 2; 673391, 3.
