Abstract:

Four novel compounds, [Cd(tp)(bpp)]n (1), [Cd(tp)(bpy)] n (2), [{Cd4(bpa)4(bpy)6} ·(bpy)0.5·7H2O]n (3) and [Cd2{(Htp)(tp)1.51}(bpe)]n (4) [tp = terephthalate, bpp = 1,3-bis(4-pyridyl)propane, bpy = 4,4′-bipyridine, bpa = 4,4′-biphenyldicarboxylate, bpe = 1,2-bis(4-pyridyl)ethane], of cadmium(n) polycarboxylate coordination polymers based on mixed ligands were obtained by a hydrothermal method. Complex 1 (C21H18CdN 2O4) crystallizes in the orthorhombic Pbca space group [a = 11.9401(0) Å, b = 16.8148(3) Å, c = 20.2743(3) Å, and Z = 8]. Complex 2 (C18H12CdN2O4) belongs to the monoclinic C2/m space group [a = 20.299(3) Å, b = 10.720(1) Å, c = 11.764(2) Å, β = 110.944(2)° and Z = 6]. Complex 3 (C121H98Cd4N13O23) belongs to the monoclinic P21/c space group [a = 23.2208(0) Å, b = 11.8103(1) Å, c = 45.4670(6) Å, β = 104.516(1)°, and Z = 4]. Complex 4 (C32H23Cd2N2O 10) belongs to the monoclinic P21/n space group [a = 6.9896(1) Å, b = 22.6294(1) Å, c = 19.7738(3) Å, β = 99.380(1)°, and Z = 4]. The CdII centers in the four compounds are bridged by mixed polycarboxylate ligands with bpy and related species to form the twofold parallel interpenetration topology of an undulating 2D 4 4 net for 1, a twofold interpenetration topology of a 3D β-Po net for 2, a fourfold interpenetration topology of a 3D 5-connected borazone 4664 net for 3 and an interesting 3D spiral pipe-like structure with a bolt for 4. These four compounds exhibit strong fluorescent emissions at 549 and 582 nm (λex = 532 nm) for 1, 493 nm (λex = 360 nm) for 2, 413 and 424 nm (λex = 315 nm) for 3 and 350 nm (λex = 220 nm) for 4 in the solid state at room temperature. These are novel structural topologies and could be significant in the field of photoactive materials. © Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
