Abstract:
Two new bimetallic coordination polymers, {[NO2BzQl][MCr(ox)3]}∞,where [NO2BzQl]+=1-(p-nitrobenzyl)quinolinium, ox2-=oxalate, M=Ni2+(A) or Cu2+(B), were synthesized, and characterized by elemental analysis, infrared spectra. The bonds ofνas(C=O)、δ(C=O) are at 1644、815 cm-1 for complex (A), and 1635、811 cm-1 for complex (B), respectively. The results of IR for (A) and (B) indicated that two complexes form 2-D layer structures in the solid state. The results of the variable temperature magnetic susceptibilities for (A) and (B) revealed that there exist antiferromagnetically coupled interactions both intra- and interlayer. The best fit parameters using Curie-Weiss formula are as follows: C=0.662 emu K/mol, θ=-1.658 K, and agreement factor R=2.0×10-5for (A).C=0.17 emu K/mol, θ=-0.693 K, and R=1.86×10-6for (B).

摘要:
合成了两种新的草酸根桥联的双金属层状配位聚合物,{[NO2BzQl][MCr(ox)3]}∞,其中[NO2BzQl]+为1-(p-nitrobenzyl)quinolinium,ox2-为Oxalate,M为Ni2+或Cu2+,并经元素分析、红外光谱表征.变温磁化率测定结果表明,在这两种层状配位聚合物中,相邻的金属离子之间存在反铁磁偶合作用.应用Curie-Weiss公式拟合相应的变温磁化率数据为:C=0.662 emu K/mol,θ=-1.658 K,R=2.0×10-5(Ni2+);C=0.17 e
