摘要：

In the symmetrical crystal structure of [{U(eta(5)-C(4)Me(4)P)(mu-eta(5),eta(1)-C(4)Me(4)P)(BH4)}(2)], the U-P bond distances for the terminal and bridging eta(5)-phospholyl ligands are 2.945(3) and 2.995(3) Angstrom respectively, and the U-P (eta(1)-phospholyl) bond length is equal to 2.996(3) Angstrom; the tridentate borohydride ligands are cis to the (UP)(2) ring. The cis and trans isomers of [{U(Cp*)(mu-eta(5),eta(1)-C(4)Me(4)P)(BH4)}(2)] (Cp* = eta(5)-C(5)Me(5)) are in equilibrium in toluene.
