• W3093531481 abstract "The reaction of [Ni6(CO)12]2– as a [NBu4]+ salt in CH2Cl2 with 0.8 equiv of PCl3 afforded [Ni14P2(CO)22]2–. In contrast, the reactions of [Ni6(CO)12]2– as a [NEt4]+ salt with 0.4–0.5 equiv of POCl3 afforded [Ni22–xP2(CO)29–x]4– (x = 0.84) or [Ni39P3(CO)44]6– by using CH3CN and thf as a solvent, respectively. Moreover, by using 0.7–0.9 mol of POCl3 per mole of [NEt4]2[Ni6(CO)12] both in CH3CN and thf, [Ni23–xP2(CO)30–x]4– (x = 0.82) was obtained together with [Ni22P6(CO)30]2– as a side product. [Ni23–xP2(CO)30–x]4– (x = 0.82) and [Ni22P6(CO)30]2– were separated owing to their different solubility in organic solvents. All the new molecular nickel phosphide carbonyl nanoclusters were structurally characterized through single crystal X-ray diffraction (SC-XRD) as [NBu4]2[Ni14P2(CO)22] (two different polymorphs, P21/n and C2/c), [NEt4]4[Ni23–xP2(CO)30–x]·CH3COCH3·solv (x = 0.82), [NEt4]2[Ni22P6(CO)30]·2thf, [NEt4]4[Ni22–xP2(CO)29–x]·2CH3COCH3( x = 0.84) and [NEt4]6[Ni39P3(CO)44]·C6H14·solv. The metal cores’ sizes of these clusters range from 0.59 to 1.10 nm, and their overall dimensions including the CO ligands are 1.16–1.63 nm. In this respect, they are comparable to ultrasmall metal nanoparticles, molecular nanoclusters, or atomically precise metal nanoparticles. The environment of the P atoms within these molecular Ni–P–CO nanoclusters displays a rich diversity, that is, Ni5P pentagonal pyramid, Ni7P monocapped trigonal prism, Ni8P bicapped trigonal prism, Ni9P monocapped square antiprism, Ni10P sphenocorona, Ni10P bicapped square antiprism, and Ni12P icosahedron." @default.
