“…The comparison of this new structure type with that of the 〈100〉 layer perovskite structure 26 and a second with a very distorted layer perovskite structure containing anions with four short Hg-Cl contacts (i.e. quasi-four-coordinate mercury), 27 while the analogous salt [NH 3 (CH 2 ) 3 NH 3 ] 2 [HgCl 4 ]Cl 2 has the layer perovskite structure. 28 Of the other 30 structures in the CSD containing ions of empirical formula [HgCl 4 ] 2Ϫ , 28 have tetrahedral anions (albeit often rather distorted from T d symmetry), one is trimeric and one is dimeric.…”

“…The Hg…Hg distance in compound HgBr1 is calculated as 3.970(1)Å which shows that the structure is stabilized by metallophilic interactions apart from X-H…A and Br…Br [minimum distance = 3.610(2)Å] secondary interactions 10,19 . Mercury atom at symmetry position 1+x, 0.5-y and 0.5+z establish a close contact with Hg located at 1-x, 0.5+y and 0.5-z as shown in Figure 3.…”

Abstract:To analyze the metallophilic interactions in [HgX] -, (X = Cl, Br, I), series of inorganicorganic hybrid materials were analyzed through single crystal x-ray crystallographic techniques. It has been observed that few compounds HgCl1, HgCl2, HgCl3 and HgCl9 of mercuric chloride series validate the phenomenon of mercurophilic interactions with minimum Hg…Hg distance of 3.831(1), 3.920(2), 3.810(3) and 3.984(1)Å respectively, whereas in mercuric bromide series, this phenomenon is predominant in the compounds of HgBr1, HgBr4, HgBr5, HgBr9 and HgBr11 with minimum Hg…Hg distance of 3.970(1), 3.860(1), 3.799(1), 3.884(1) and 3.873(1)Å respectively. Only three compounds in mercuric iodide series confirms the phenomenon of mercurophilic interactions with Hg…Hg = 3.938(1) in HgI8, Hg…Hg = 4.011(1) in HgI11 and Hg…Hg = 3.649(2)Å in HgI13 where as the metallophilicity is missing in other remaining compounds of all the three series. The Hg-Cl bond distances experiential in the range of 2.346(7) to 2.852(5)Å and Cl-Hg-Cl bond angles in the range of 79.2 to 180 o .

“…Within this frame, there has been extensive research on Sn(II), Pb(II), and Ge(II) halides but less on Zn(II), Cd(II), and Hg(II) − being prospective homovalent candidates. In previous papers, Hg(II) halides containing alkylammonium cations inter alia , (C 3 H 12 N 2 )(HgC1 4 ) and (C 4 H 14 N 2 )(HgCl 4 ), presented corner-sharing HgCl 6 octahedra with (HgCl 4 ) 2– units forming layers separated by the bifunctional ammonium cations. The larger aliphatic chain of (C 4 H 14 N 2 ) 2+ favored van der Waals interactions, better stacking the cations and favoring the shorter separation of the inorganic layers.…”

Influence of Aromatic Cations on the Structural Arrangement of Hg(II) Halides

Understanding the structure and arrangement of hybrid metal halides and their contribution to the optoelectronic properties is, thus far, a challenging topic. In particular, new materials composed of d10 metal halides and pyridinium cations are still largely unexplored. Therefore, we report the synthesis and characterization of six Hg(II) salts built up from (Hg2Cl6)2– or (HgX4)2– anions (X = Cl, Br, I) and 2,2′-bipyridium (2,2′-Hbipy)+, 2,2′-bipyridine-1,1′-diium (2,2′-H2bipy)2+, or 1,10-phenantrolinium (1,10-Hphen)+ cations, using the same experimental conditions. All of them have been characterized by PXRD, EA, FTIR-ATR, and 1H NMR spectroscopies; single-crystal X-ray diffraction; and TG/DTA determinations. The study of their packing via Hirshfeld surface analysis and 3D deformation density mapping revealed the contributions of the intermolecular interactions to the structural arrangement, notably, the effect of the cation planarity on them. Successively, periodic DFT calculations showed that (i) the valence and conducting bands are mainly composed of the p orbitals of the halide and the organic cation, respectively, and (ii) the corresponding band gap depends mainly on the halide.
