摘要：

The remarkably stable paramagnetic Rh(II) complex [Rh(eta(3)-TMPP)2][BF4)2 (TMPP = tris(2,4,6-trimethoxyphenyl)phosphine) reacts with 2 equiv of tertbutyl isocyanide to yield the air-stable mononuclear Rh(II) complex [Rh(eta(3)-TMPP)2(CNBU(t))2][BF4]2. A single-crystal X-ray diffraction study reveals that the cation adopts a distorted-square-planar geometry in which the phosphine ligands are trans rather than cis as in the parent complex. The paramagnetism of this unusual four-coordinate Rh(II) metallo radical was probed by a variety of spectroscopic and magnetic techniques.
