Abstract

The solid-state structure of the cluster benzene complex R u~(CO),(~~-$ $? Q~-C &)(1) has been determined at room temperature (RT) and 193 K (LT) by sin le-crystal X-ray diffractometry. 1 is monoclinic, space group B1, 2= 2, a= 9.027 (1) A, b= 12.665 (2) 1, c= 9.049 (3) A, 0= 118.15 (2) O for RT and a= 8.985 (1) A, b= 12.527 (2) A, c= 9.011 (1) A, 0= 118.217 (9) O for LT. The benzene ligand shows a clear Kekul&type distortion:'long” and “ ...
