Reaction of the potassium pentamethylcyclopentadienyl iridate tris-hydride K[IrCp*H3] with UCl4 and ThCl4(DME)2 led to the complete replacement of the halide ligands to generate multimetallic complexes U{(μ-H)3IrCp*}4 (1) and Th{[(μ-H2)(H)IrCp*]2[(μ-H)3IrCp*]2} (2), respectively. These analogues feature a significant discrepancy in hydride bonding modes; 1 contains twelve bridging hydrides while 2 contains ten bridging hydrides and two terminal, Ir-bound hydrides. Use of a U(III) starting material, UI3(1,4-dioxane)1.5, resulted in the octanuclear complex {U[(μ2-H3)IrCp*]2[(μ3-H2)IrCp*]}2 (3). Computational studies indicate significant bonding character between U/Th and Ir in 1 and 2, with f-orbital involvement in the singly-occupied molecular orbitals of the uranium species 1. In addition, these studies attribute the variation in hydride bonding between 1 and 2 to differences in dispersion effects.

Chemical Science
Our journal has a wide-ranging scope which covers the full breadth of the chemical sciences. The research we publish contains the sorts of novel ideas, challenging questions and progressive thinking that bring undiscovered breakthroughs within reach. Your paper could focus on a single area, or cross many. It could be beyond the accepted bounds of the chemical sciences. It might address an immediate challenge, contribute to a future breakthrough or be wholly conceptual. We’re a team from every field of the chemical sciences, and know from experience that breakthroughs that drive the solutions to global challenges can come from anywhere, at any time. You could even start an entirely new area of research. Too bold? Too progressive? No such thing
