The coordination polymers ∞2[(CuCN)2(μ‐2 Mepyz)], ∞3[CuCN(μ‐2 Mepyz)] and ∞3[CuCN(μ‐4 Mepym)] (1–3) (2 Mepyz = 2‐methylpyrazine; 4 Mepym = 4‐methylpyrimidine) may be prepared by self‐assembly in acetonitrile solution at 100 °C (1, 3) or without solvent at 20 °C (2). All three contain ∞1[CuCN] chains that are bridged by the bidentate aromatic ligands into sheets in 1 and 3 D frameworks in 2 and 3. Reaction of CuSCN with these heterocyclic diazines at 100 °C leads to formation of the lamellar coordination polymers ∞2[(CuSCN)(μ‐2 Mepyz)] (4) and ∞2[CuSCN · (4 Mepym‐κN1)] (5), which contain respectively ∞1[CuSCN] chains and trans‐trans fused ∞2[CuSCN] sheets as substructures. The presence of an asymmetric substitution pattern in 2 Mepyz and 4 Mepym induces the adoption of a chiral structure by 2 and 5 (space groups P212121 and P1).

“…Bowes & Ozin (1996) reviewed the topologies of cyanide and chalcogenide structures in terms of their dimensions, linking units, open channels and, if existing, their interpenetrating nets. Iwamoto et al (1997) showed similarities between certain cyanide structures and di-, group, chain, ring, layer and framework silicates. Furthermore, they identi®ed cyanide compounds with nets analogous to well known simple structure types such as PtS, cuprite, pyrite and rutile.…”

We propose a general approach to nets and structures in which vertices represent stereochemically signi®cant groups or clusters of atoms, and edges represent the linkage between these groups. Vertices may be single atoms, dimers, coordination polyhedra, clusters of atoms or clusters of coordination polyhedra; edges may be single chemical bonds or sets of several chemical bonds.Thus, a single net may be the basis for a family of structures that are homeomorphic to that net. The coordination of polyhedra or units around a vertex is visualized by connecting the centres of the atoms or groups at the vertices connected with the central vertex. Thus, the concept of coordination number is extended to include coordinating groups. We name a net after a homeomorphic simple structure-type for which there is a one-to-one correspondence between the vertices of the net and speci®c atoms of the structure, and between the edges of the net and the chemical bonds. We term the resulting more complex structures metastructures in order to distinguish them from their corresponding simple structure-types. Individual metastructures are referred to as alpha structures similar to a particular simple type. Thus, the open complex framework of [V 5 O 9

“…Incidentally, for Cd(CN) 2 , there was no guest molecule found to facilitate a doubly interpenetrated diamond-like framework. Furthermore, the coordination geometry of Cd(II) was Cd T [3][4][5][6][7]. Thus, we surmised that the hydrophilic groups of guest molecules influence the Cd(II) coordination environment.…”

“…However depending on the influence of other ligands (for example, H 2 O [8, [13][14][15][16][17][18][19]), the geometry might also be trigonal-bipyramidal five-coordination geometry (Cd TB ), or octahedral six-coordination geometry (Cd OC ). For Cd(CN) 2 clathrates containing a lipophilic guest, the coordination geometries of Cd(II) were Cd T and the Cd(CN) 2 frameworks were cristobalite-like or tridymite-like structures [4][5][6][7][8][9][10][11]21]. In contrast, the Cd(CN) 2 clathrates with the water molecule(s) coordinating to Cd(II) ion contain alcohol or short dialkyl-ether (alkyl group with a carbon number less than 3) as a guest, and the host frameworks function as zeolite-mimetic structures [8,[13][14][15][16][17][18][19].…”

“…The discovery of the clathrate Cd(CN) 2 ·CCl 4 [4] is very important in the history of the simple, yet subtle, cadmium(II) cyanide clathrates and their related systems. Cadmium(II) cyanide is a 3D porous coordination polymer clathrating various guest molecules (for example, CCl 4 [4][5][6], C 6 H 6 [9] CH 2 ClCHCl 2 [10], and Bu 2 O [10]) by van der Waals force in its cavity space. Interestingly, the Cd(CN) 2 host structures change according to the guest [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], and the hosts form a mineralomimetic framework.…”

Abstract:Two novel 3D cadmium(II) cyanide coordination polymers with branched-butoxyethanol compounds (iBucel = iso-butoxyethanol, tBucel = tert-butoxyethanol), [{Cd(CN) 2 (iBucel) 2 }{Cd(CN) 2 (H 2 O)(iBucel)} 2 {Cd(CN) 2 } 6 ·2(iBucel)] n I and [{Cd(CN) 2 (H 2 O) 1.06 (tBucel) 0.94 } {Cd(CN) 2 (tBucel)} 2 {Cd(CN) 2 } 2 ·1.06(tBucel)] n II, were synthesized and characterized by structural determination. Complex I contains two distinct Cd(II) coordination geometries: octahedral and tetrahedral. In contrast, complex II contains three distinct Cd(II) coordination geometries: octahedral, square-pyramidal, and tetrahedral. In the two complexes, branched-butoxyethanol molecules behave as both a ligand and a guest in the Cd(CN) 2 cavities. The framework in I contains octahedral and tetrahedral Cd(II) in a 3:6 ratio. In I, the coordination environments of octahedral Cd(II) are cis-O-Cd-O. The framework in II contains octahedral, square-pyramidal, and tetrahedral Cd(II) in a 1:2:2 ratio. In II, the coordination environment of octahedral Cd(II) is disordered trans-O-Cd-O and the axial oxygen ligand is either a water or tBucel molecule. In II, the square-pyramidal Cd(II) geometry is formed by one tBucel ligand and four cyanide ligands. The Cd(CN) 2 frameworks of the two complexes exhibit different structures.
