Tetranuclear cyanide rhenium(I)–copper(I) coordination compounds were synthesized in the course of simple one-pot reactions in mild conditions. A new class of mixed-metal compoundsbased on rhenium(I) clusters that are comprised of the pseudo-rhombic-shaped Re2Cu2(μ-CN)4} unit were found. Two kinds of geometries adopted by the self-assembled cyclic clusters are observed, both of which can be described as
在温和的条件下,通过简单的一锅反应即可合成四核氰化物rh(I)-铜(I)配位化合物。发现了一类新的基于rh(I)团簇的混合金属化合物,该化合物由假菱形的Re 2 Cu 2(μ-CN)4 }单元组成。观察到自组装循环簇采用的两种几何形状,它们都可以描述为具有不同协调模式的近似块状总体几何形状。独特的多核结构ReCu(CH 3 CN)(μ-CN)2(CO)2(PPh 3)2 } n可以在反应条件下形成。通过单晶X射线衍射和光谱研究表征了所提出的化合物。

first cyanide rhenium(I)–silver(I) clusters were synthesized in the course of simple one-pot high-yielding reactions. This new class of obtained self-assembled, cyclic octanuclear complexes is composed of pseudo-square-shaped Re4Ag4(μ-CN)8} units, which, along with PPh3 ligands, adopt an approximately block-like overall geometry. We discovered that the studied cavity-shaped clusters feature a channeling
在简单的一锅高产反应过程中,合成了第一个氰化物((I)-银(I)簇。这类新型的自组装环状八环复合物由伪正方形的Re 4 Ag 4(μ-CN)8 }单元组成,该单元与PPh 3配体一起采用近似块状的整体几何形状。我们发现,所研究的腔状团簇具有能够容纳较小分子的通道晶体网络,并具有经历可逆的客体溶剂吸附的能力。根据反应条件,四核络合物[Re 2 Ag 2(μ-CN)4(CO)4(PPh 3)6 ]和形式基序的种类ReAg 1.5(CN)2.5(CO)2(PPh 3)2 }可以形成。

New formate (1-3; 4b, 6 and 7), acetate (8, 9) and trifluoroacetate (12, 13 and 15) complexes have been synthesized and characterized by elemental analysis and by IR and H-1 and C-13 NMR spectroscopies. New data or new synthetic procedures are provided for several known complexes (4a, 5, 19, 11 and 14). X-ray structural data for cis-Ru(bpy)(2)(CO)(OCHO)(PO2F2) (4b) clearly identify the eta(1)-bound formate ligand bound to an octahedral ruthenium center and the data for fac-Re(CO)(3)(PPh3(OCOMe) (9) show an eta(2)-bound acetate ligand bound to an octahedral rhenium center. Infrared spectral data for four types of formate complexes, three bonding types of acetates and the two known types of trifluoroacetate ligands are discussed. Comparisons of the v(OCO) bands for the carboxylate ligands in all of the complexes show that these bands are useful in identifying the bonding type of each carboxylate ligand.
