Title: Ca(BH 4) 2 as a simple tool for the preparation of thorium and uranium metallocene borohydride complexes: First synthesis and crystal structure of (C 5Me 5) 2Th(η 3-H 3BH) 2

Here, calcium borohydride allows for the high-yielding synthesis of (C 5Me 5)2An(η 3-H 3BH) 2 (An = Th, U) by reaction with (C 5Me 5) 2AnCl 2 (An = Th, U). While a preparative synthesis of (C 5Me 5) 2U(η 3-H 3BH) 2 has been previously reported in the literature using K(C 5Me 5) and U(BH 4) 4, the use of Ca(BH 4) 2 is higher yielding and mild. Full characterization of the novel compound (C 5Me 5) 2Th(η 3-H 3BH) 2 is presented.
