Crystal engineering through [Hg(SCN)4]2−templates: S⋯S interaction mediated 3-D parallel interpenetration in the self-assembled superstructure of [Hg(SCN)4]2−and protonated 2,2′- dipyridylamine

“…The present complex is the third reported instance where the S … S interaction has led to interpenetrating architecture, the earlier ones being a parallel interpenetration of a (4,4) net 13 and a diamondoid net. 14 In summary, we report an interesting crystal structure in which the (4,4) net topology of the 2-D layers of the complex have been successfully accomplished through the deliberate use of [Hg(SCN) 4 ] 22 nodes as templates. This indicates that the [Hg(SCN) 4 ] 22 unit can be effectively used as a potential scaffold for the design of supramolecular architectures in future.…”

Rational Assembly of Primitive Cubic Networks Using Hexameric Stacks of Sodium Aryloxides as Nodes

“…All of these issues can lead to poor predictability and reproducibility in network synthesis. Hence, although the potential for the rational design of frameworks composed of s-block metals and linking ligands has certainly been recognized, it was only recently that this goal was finally realized. , Specifically, our group used lithiated aryloxides to selectively preassemble tetrasolvated Li 4 O 4 cubane aggregates that were subsequently connected through the divergent Lewis base dioxane to build polymeric assemblies …”

“…83 Halogen-donor ligands X-Ray structural analysis of [{Li(diox) 2.5 TaCl 4 S} n ]•0.5n diox and [{Li 2 (diox) 3 Cl} n ]-[TaCl 6 ] n reveals diox molecules linking the cations to form layers of puckered hexagonal nets; in the latter compound the layers are linked by almost linear Li-Cl-Li units to form a three-dimensional structure. 84 The crystal structure of [HC(CHNPh) 2 ]AlCl(Me)•2[Li{B(C 6 F 5 ) 4 }]•C 6 H 6 reveals one lithium cation coordinated to six halogen atoms (Cl + 5 F) in a distorted trigonal prismatic arrangement. The other lithium is surrounded by h 6 -C 6 H 6 and four fluorines, two of which are involved in the shortest Li…F(C) contacts observed so far (1.895(3) and 1.956(3) Å).…”
