New Structures Added to the Cambridge Structural Database
The Latest Cambridge Structural Database Update
The Cambridge Structural Database (CSD) now contains 1,410,034 structures (1,451,367 entries), supporting scientific research internationally across many different fields including pharmaceuticals, agrochemicals, materials science, and more.
14029 new structures (15248 entries) have been added to the CSD in this update. Out of these 15248 entries, 8368 (55%) are organic and 6880 (45%) are organometallic.
Included in this update is this impressive structure (CSD Entry FAHSAN) featuring a cyclo tribismuth ring with all-metal aromaticity, reported by Liddle et al. (http://dx.doi.org/10.1038/s41557-026-02123-8). The ring represents the heaviest 6p analogue of cyclopropenium and is isolated as inverse-sandwich complexes with uranium and thorium. The aromaticity is calculated to be dominated by sigma-orbital contributions with a ring current comparable to that of benzene.
Another fascinating structure is CSD Entry UBUGOS, a carbon-free analogue of ferrocene, [Os(B5H10)2], reported by Jemmis and Ghosh et al. in Science (http://dx.doi.org/10.1126/science.aed9192).
CSD Entry QAJNID provides unambiguous stereochemical proof of the revised side-chain configuration after the first asymmetric synthesis of a mangicol sesterterpene reported by Maimone et al. in JACS (Asymmetric Total Synthesis and Structure Revision of (+)-Mangicol D).
