Synthesis, Structure and Magnetic Analysis of the Cobalt Polymer Based on N-[(3-pyridine)-sulfonyl]aspartate

【摘要】 One new cobalt polymer [Co（L）·3H₂O]_n（1, H₂L=N-[（3-pyridine）-sulfonyl]aspartate） has been synthesized and characterized by single-crystal X-ray diffraction and elemental analysis. Polymer 1 belongs to the monoclinic system, space group P21/n with a=11.479（2）, b=7.3180（15）, c=16.424（3） ?, β=109.56（3）°, V=1300.1（5） ?³, Mr=385.22, Z=12, F（000）=790, S=1.054, R=0.0670, wR=0.1147,（Δρ）max=1.158 and（Δρ）min=–0.754 e/?³. TGA showed that the polymer first lost one coordinated water molecule and then another two coordinated water molecules. The values of the Curie and Curie-Weiss constants of polymer 1 are Cm=2.67 cm³mol^–1 K and θ=–21.66 K.更多还原
