A trinuclear strontium hydride [(Me4TACD)3Sr3(µ2-H)4(thf)][B(C6H3-3,5-Me2)4]2 (Me4TACD = 1,4,7,10-tetramethyl-tetraazacyclododecane) and a mixed calcium strontium hydride [(Me4TACD)2CaSr(µ-H)2(thf)]2+ were isolated by hydrogenolysis of cationic benzyl precursors. A solution of [(Me4TACD)2CaSr(µ-H)2(thf)][B(C6H3-3,5-Me2)4]2 shows hydride ligand...

Neutron diffraction analysis of TaCp2(H)(SiMe2H)2 (1) has revealed a symmetric structure with a classical, rather than agostic, hydride ligand: the Ta–H distance is 1.785(15) Å, the non-bonding H···Si distances are 2.189(18) and 2.190(17) Å, and the H–Ta–Si angles are 55.2(5) and 55.5(5)°; final R factor = 8.9% for 1295 reflections.
