SYNTHESIS AND CRYSTAL STRUCTURE OF[Sm2(Val)4(H2O)8]6ClO4
Abstract:
The title complex has been synthesized and characterized by FT-IR spectrometry. The crystal of the complex, determined by X-ray diffraction method, belongs to orthorhombic with space group Pnn2 and cell parameters a=1.4433(1)nm, b=2.0169(3)nm, c=1.8489(2)nm and Z=4.The two Sm ions are connected by four carboxyl groups forming a dinuclear complex. Four water molecules are coordinated to cach Sm ion in this dinuclear complex. Therefore, there are 8 oxygen atoms coordinated to each Sm ion assuming a bicapped trigonal prism. The N atoms of NH3+ groups in the complex does not coordinate to Smions. The two Sm ions are spaced in 0.4443nm, thus no metalmetal bonds could be formed in the complex.
