Two new coordination polymers Ni(bix) 3 ⋅ 2(NO 3 ) ⋅ (H 2 O) 1 and Co(bix) 2 ⋅ 2(NO 3 ) 2 (bix = 1,4-bis(imidazole-1-ylmethyl)benzene) have successfully been synthesized via hydrothermal reactions. These two compounds have similar local coordination environments but different topological networks due to the flexibility of the bix ligand. Additionally, magnetic studies reveal that 1 and 2 also exhibit different magnetic behaviors. Although magnetic exchange pathways are same as M II -bix-M II (M = Ni 1, Co 2), 1 shows purely paramagnetic state almost down to 2 K with weak antiferromagnetic interaction; while stronger antiferromagnetic interaction in 2 is suggested. Meanwhile, an anomaly around 38 K in zero-field-cooled mode is observed but suppressed in field-cooled mode, which may be suggesting the spin canting for 2. The field dependent magnetizations show magnetization of 2.17 μ B and 2.44 μ B at 7 T for 1 and 2, respectively. Also, the magnetic interaction J/k B of À 3.3 K is estimated for 2.

With pyridinium zwitterionic ligand H 2 LCl 2 (1,1'- ((2,3,5,6-tetramethyl-1,4-phenylene)bis(methylene))bis(4carboxypyridin-1-ium)chloride) as the main connection point, a novel Cd ( ) coordination polymer namely) and a partially deprotonated HLClO 4 •H 2 O were obtained by room temperature volatilization method. X-ray diffraction studies reveal that HLClO 4 •H 2 O crystallizes in the monoclinic P2 1 /n space group, with a bowl shape partially deprotonated HL + cation as the main structure, and the ClO 4 anion which balances the charge just exists outside. When the ligand reacts with CdSO 4 8/3H 2 O, CP 1 crystallized in the triclinic P-1 space group with two distinct Cd ( ) centers was obtained. Abundant hydrogen bonds produce the 3D supramolecular structure of CP 1. Elemental analysis, powder X-ray diffraction, infrared spectrum, thermogravimetric analysis, solid-state uorescence properties and CIE analysis of CP 1 were studied. Results indicate that the CP 1 has good thermal stability and has potential applications in blue luminescent materials.
