Supplement. Tables of bond lengths determined by X-ray and neutron diffraction. Part 2. Organometallic compounds and co-ordination complexes of the d- and f-block metals
TL;DR: In this paper, the average lengths for metal-ligand bonds are reported, together with some intraligand distances, for complexes of the d-and f-block metals, for 325 different bond types involving metal atoms bonded to H, B, C, N, O, F, Si, P, S, Cl, As, Se, Br, Te, or I atoms of the ligands.

TL;DR: Validation experiments indicate that, with rare exceptions, search results afford precise and unbiased estimates of molecular geometrical preferences.
Journal ArticleDOI
Metal-bound chlorine often accepts hydrogen bonds
TL;DR: In this paper, crystallographically characterised hydrogen bonds containing M-Cl, C-Cl or Cl-Cl and either HO or HN groups were analyzed and it was shown that M−Cl moieties are good, anisotropic hydrogen-bond acceptors forming hydrogen bonds similar in length to those of the chloride anion.
