Solid-state aggregation of mercury bis-acetylides, Hg(CCR)2, R=Ph, SiMe3

Spatial Extent of the Singlet and Triplet Excitons in Luminescent Angular‐Shaped Transition‐Metal Diynes and Polyynes Comprising Non‐π‐Conjugated Group 16 Main Group Elements

“…The van der Waals radius of mercury has been debated and a value of up to 2.2 has been proposed recently, [37] and is predicted to be a better estimate than the value quoted by Bondi. [38] Here, the observed Hg···Hg separations are comparable to the values of 3.71-4.25 for [Hg(C CR) 2 ] (R= Ph, SiMe 3 ), [39] and 4.077 and 4.449 computed for molecular (HgH 2 ) n clusters (n = 2, 3), [40] and are towards the upper limit of those accepted as representing metallophilic interactions. [41] None of these structures show p-p stacking of the arene rings in the solid state.…”

Evolution of lowest singlet and triplet excited states with transition metals in group 10–12 metallaynes containing biphenyl spacer

“…4). Although alkynylgold(I) complexes exhibiting AuÁ Á ÁAu interactions are numerous [16], literature reports showing HgÁ Á ÁHg bonding interactions are, to our knowledge, comparatively very limited [17]. While the HgÁ Á ÁHg contacts here indicate that each of the individual interactions is relatively weak in nature, it is the large number of them that play a supramolecular role and generate a significant driving force for the observation of solid-state aggregation.…”

Synthesis and crystal structure of [C6H5Hg(H2NSiMe3)][H2N{B(C6F5)3}2], a phenyl–mercury(II) cation stabilised by a non-coordinating counter-anion

“…The closest Hg(1)Á Á ÁHg(1) interatomic distance of 4.3688(10) Å rules out the existence of a metallophilic interaction, since it is clearly outside the upper limit of distances regarded as indicative of mercurophilic bonds (3.7-4.0 Å ) [21].…”
