The crystal structures of three hybrid organoammonium metal halide salts composed of edge-sharing MX(6) octahedra have been determined. The genesis of these structures can be traced to the parent hexagonal MX(2) structure via dimensional reduction and recombination arguments. The structures of (Et(2)NH(2))(3)Pb(3)X(9) x nH(2)O (X = Br, I) contain unique columnar (Pb(3)X(9))(n)(3)(n)(-) structures, built up of edge-shared PbX(6) octahedra. The interaction of the Et(2)NH(2)(+) cations with the parent PbX(2) structures leads to a rearrangement of the lattice into the observed columnar structure. Groups of six Et(2)NH(2)(+) cations are hydrogen bonded to these columns, girdling them at their narrowest points. These hydrogen bonds contribute to the formation of the zigzag nature of the columnar inorganic framework. The resultant structures are recombinate analogues (polytypes) of the (Pb(3)X(9))(n)(3)(n)(-) stacks that would be obtained by the dimensional reduction process of the parent layer PbX(2) structure into simple edge-shared ribbons of PbX(6) octahedra. These structures can be described in terms of the stacking of planar bibridged Pb(3)X(8)(2-) units decorated with a single halide ion at a terminal lead ion site. In a similar fashion, (beta-alaH)(2)Sn(2)I(6) contains corrugated (Sn(2)I(6))(n)(2)(n)(-) columns (beta-ala = beta-alanine), with the cations sitting in the clefts of the columns.

“…HgCl 2 forms a tetranuclear (Hg 4 Cl 8 ) species through two μ 3 -chloro bridging modes between the cationic centers by two Cl – anions (Figure , right). This type of mercury polynuclear complex, although rare, has already been described in the literature …”

“…This type of mercury polynuclear complex, although rare, has already been described in the literature. 24 The crystal is a 3D pseudo-diamond-type coordination network, resulting from the interconnection of consecutive tectons 4 by pseudorectangular Hg 4 N 4 S 4 Cl 8 complexes. The distance between Hg 2+ cations within the tetranuclear unit of 4.225(4) Å is close to those reported for similar neutral Hg n Cl 2n species.…”

“…So chloromercurates(II) usually exhibit a wide range of geome-tries, stereometries and connectivities (Grdenic, 1965;Linden et al, 1999). Among these fascinating structures, one-dimensional chloromercurate(II) inorganic chains show a great variety of architectures, and it is impossible to predict their coordination geometry due to the wide range of different HgÁ Á ÁCl contacts (Aharoni et al, 1989;Bats et al, 1980;Rabe & Muller, 1999;Zabel et al, 2005). , Linden et al (1999 reported several chloropyridinium chloromercurate(II) compounds, showing that an [Hg x Cl y ] nÀ polymer was usually made up of the subunits HgCl 2 , Cl À , [HgCl 3 ] À and [HgCl 4 ] 2À .…”

The structure of the title compound, {(C(5)H(5)ClN)(2)[Hg(3)Cl(8)]}(n), consists of 4-chloropyridinium cations and one-dimensional [Hg(3)Cl(8)](2-) anion chains. There are two coordination environments for Hg(II) in the inorganic chain. The first is a distorted tetrahedral geometry made up of an HgCl(2) unit with two Cl(-) anion bridges, while the second is an octahedral coordination geometry consisting of an HgCl(2) unit and four chloride-anion bridges. This gives rise to a novel three-layer centrosymmetric polymer. Finally, the three-dimensional network comes about through the many C-H···Cl and N-H···Cl hydrogen bonds that link the organic and inorganic layers.
