摘要
在水热条件下,成功合成出1例1D的新型草酸钴化合物—[Co(C2O4)0.5(H2O)]n(1).X-射线单晶衍射的分析表明,化合物(1)属于单斜晶系,C2/c空间群,晶胞参数为a=1.178 5(6)nm,b=0.542 5(3)nm,c=0.966 5(5)nm,β=126.371(5)°,Z=8.在化合物中,Co2+离子与草酸基团沿b轴交替连接而形成一个1D直链结构,这些链状结构之间又通过氢键作用而形成一个3D的超分子化合物.
In the study,a novel cobalt oxalate compound,[Co( C2O4)0. 5( H2O) ]n( 1) was synthesized. X-ray single crystal diffraction analysis results showed that the compound belongs to monoclinic,C2 /c space group with the cell parameters a = 1. 1785( 6) nm,b = 0. 5425( 3) nm,c = 0. 9665( 5) nm,β = 126. 371( 5) °,Z = 8. Each Co2 +cations was coordinated with four oxygen atoms from two oxalates and two oxygen atoms from two water molecules. The Co2 +cations and oxalate anions were alternately connected to form a 1D chain structure in the b axis direction,between which a 3D supramolecular compound was formed through hydrogen bond.
