Probing the Conformational Behavior of a Seven Hetero-Spin Supramolecule

Abstract The synthesis and crystal structure of a 7-spin supramolecular poly-rotaxane is reported. The [4]rotaxane structure involves a trigonal thread centred on a {CrNi2} core, with each of the three arms terminated by Cu(II) centres and bearing a {Cr7Ni} metallocycle. The macr...

A crystalline uranium Fischer-type carbyne

Abstract Since their discovery in 1973, transition metal Fischer carbynes have become a foundational class of metal–carbon triple bond in organometallic chemistry. However, even though the uranium Fischer carbyne bonding motif has been a fundamental target in f -element chemistry...
