| Abstract: A new coordination complex [Cu(Ⅱ)(DETA)]3[Cr(CN)6]2·5H2O (DETA=diethylenetriamine) was synthesized, its crystal structure and magnetic properties were determined. The crystal crystallizes in monoclinic space group P21/c, with unit cell constants a=2.056 6(7) nm, b=1.440 7(5) nm, c=1.513 3(5) nm, β=95.996(6)°, and V=4.459(3) nm3, Z=4, Dc=1.499 g·cm-3, F(000)=2 060，μ(Mo Kα)=1.936 mm-1, R1=0.052 3, wR2=0.106 2. The structure consists of a one-dimensional chain of [Cu(DETA)]2[Cr(CN)6]+ and binuclear [Cu(DETA)][Cr(CN)6]-. The coordination geometries around Cu2+ atoms are distorted square-based pyramidal and distorted square, respectively. Magnetism studies show that there are ferromagnetic interactions between Cu2+ and Cr3+ ions. CCDC: 272213. |
