摘要：

All good things come in fours: Thermal metal-metal borylene transfer from the terminal borylene complexes [(OC)5M=BN(SiMe3) 2] (M = Cr, W) leads to the new tetranuclear rhodium complex [Rh 4{μ-BN(SiMe3)2}2(μ-Cl) 4(μ-CO)(CO)4] (see structure), which is the first doubly borylene-bridged transition-metal complex. In the solid state, the tetranuclear units aggregate (dashed lines), giving a rare example of a neutral chain of rhodium atoms. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
