“…Hg−Hg−O (carboxylate) bond angles range from 158.4° to 174.1°. This near-linearity of the Hg−Hg−O moiety is present in the few other reported mercury(I)−carboxylate structures (166.6−177.9°; Table ). – A close contact (3.0552(9) Å) between two mercury(I) atoms is responsible for the association of adjacent mercury(I) dimers (between Hg1 and Hg5 in Figure , cf. sum of the covalent radii, 2.54 Å; sum of the van der Waals radii, 4.1 Å).…”

Preparation and Comprehensive Characterization of [Hg₆(Alanine)₄(NO₃)₄]·H₂O

et al. 2008

A new mercury-alanine complex has been isolated from reaction mixtures of mercurous nitrate dihydrate and alanine (L and D enantiomers). The solid-state structure contains mercury(I) and mercury(II) associated by alanine ligands in a polymeric array. The disproportionation of mercury(I) to mercury(II) and mercury(0) was facilitated by alanine and is evidenced by the appearance of mercury(0) in reactions of mercury(I) with the 20 common amino acids. This complex is the first mercury(I)-amino acid complex characterized in the solid state. The compounds have been comprehensively characterized using X-ray crystallography, solid-state and solution-state nuclear magnetic resonance spectroscopy, vibrational spectroscopies, and electrospray ionization mass spectrometry.

“…Despite the propensity for transition metals to adopt a variety of oxidation states, only Cu has fully characterized compounds in an oxidation state other than +2 (section ). Hg(NCS) has been reported to form, and a unit cell has been determined from powder X-ray diffraction. , Fe(NCS) 3 and compounds similar to it have long been investigated due to the utility of the characteristic blood-red color as a chemical test for iron(III), but isolation of the solid ansolvate has proved challenging . Slow crystallization of aqueous solution is reported to yield Fe(NCS) 3 , confirmed by iron content analysis, , but no structure is known.…”

Metal thiocyanates were some of the first pseudohalide compounds to be discovered and adopt a diverse range of structures. This review describes the structures, properties, and syntheses of the known binary and ternary metal thiocyanates. It provides a categorization of their diverse structures and connects them to the structures of atomic inorganic materials. In addition to this description of characterized binary and ternary thiocyanates, this review summarizes the state of knowledge for all other binary metal thiocyanates. It concludes by highlighting opportunities for future materials development.
