Actinide-transition metal bonding in heterobimetallic uranium– and thorium–molybdenum paddlewheel complexes

“…The X-An-Mo angles deviate from linearity by ca. 10°, at 171.79(4), 169.71(8), 172.18(8), and 170.81(6)°, and the An-Mo distances were found to be 3.1682(4), 3.159 2, 3.2986 (11), and 3.310(2) Å, respectively, which compare well to the sum of the covalent radii of U/Th and Mo of 3.08 and 3.12 Å, respectively. 13 The Th-Mo bonds are ~0.16 Å longer than the U-Mo bonds when the halide is kept constant, which is more than the difference in the sum of the covalent radii of U (1.70 Å) and the larger Th (1.75 Å).…”

“…1.923 Å]. 11 The Formal Shortness Ratio (FSR MM' = MM' distance/sum of MM' covalent radii) allows normalised comparison of metal-metal distances. 1 Using Pyykkö's values, 13 the FSR for UClMo (1.03) and UIMo (1.03) are shorter than for ThClMo (1.05) and ThIMo (1.06) but each are consistent with other reported An-M bonds where Th-M linkages typically exhibit greater FSR values (mean values: U-Co: 1.06; U-Re: 1.00; U-Ru: 1.03; U-Ag: 1.06; U-Rh: 0.92; U-Fe: 1.08; U-Ni: 0.91; U-Pd: 0.93; Th-Co: 1.08; Th-Ni: 1.12; Th-Pt: 1.00; Th-Ru: 1.01; Th-Cu: 1.10).…”

Effect of pore sizes on catalytic activities of arenetricarbonyl metal complexes constructed within Zr-based MOFs

“…These peak shifts were attributed to high electron-donating power of biphenylene moieties of UiO-67. 25 These CO…”
