Although several ruthenium complexes of the type Ru(acac)(2)(L)(x), where x is 1 for a bidentate or 2 for a monodentate ligand, are known, the tmed complex is conspicuously absent. This article describes the synthesis of this complex from trans-RuCl(2)(tmed)(2), acetylacetone, and triethylamine in toluene. A new synthesis of trans-RuCl(2)(tmed)(2) is also described. Some physical properties and the X-ray crystal structure of Ru(acac)(2)(tmed) are provided. 相似文献

Summary The x-ray crystal structure of tris(N-methylformamide) (N, N, N', N'-tetramethylethylenediamine)copper(II) perchlorate has been determined using three-dimensional x-ray diffraction data. The complex crystallizes in space group P21/c with Z=4. The cell dimensions are=8.255(3),b=17.951(6),c=16.541(4) Å, and =91.03(2)°. Least-squares refinement of the structure has yielded a final R value of 4.52% for 2108 independent reflect ions. The square pyramidal structure consists ofN, N, N', N'-tetramethylethylenediamine and twoN-methylformamide ligands forming a basal square plane with Cu–N bond lengths of 2.029(5) and 2.033(5) and Cu–O 1.981(4) and 1.985(4) Å, and a thirdN-methylformamide on the apex with a Cu–O distance of 2.181(4)Å. Each of the molecular plances of the three N-methylformamides lies nearly coplanar with thexy, yz andxz molecular coordination planes. The bonding properties of the title compound and its i.r. and uv-vis spectra are discussed with reference to the structure. 相似文献
