[CuCN·Me₃SnCN·C₄H₄N₂]:  A Threefold- Interpenetrating, Distorted-Diamondoid Framework (C₄H₄N₂ = Pyrazine)

Abstract

Notably distorted, adamandoid Cu10 cages with Cu···Cu edges of 10.795(6) Å (Cu−CN−Sn(Me3)−NC−Cu) and 7.142(5) Å (Cu−pyrazine−Cu) are the basic building blocks of the novel supramolecular assembly [CuCN·Me3SnCN·C4H4N2] (C4H4N2 = pyrazine). Interpenetration of three equivalent, distorted-diamondoid frameworks affords comparatively compact crystal packing.

Double Stranded Helical Organo-lead 3D-Supramolecular Coordination Polymer Containing Copper Cyanide and Phenanthroline Ligand as Antimicrobial Agent

“…The case which is supported by X-ray results indicating bent CuCN groups (C3-Cu2-C9 = 127.07 o ). This is further supported by the fact that the frequencies of the t CN appear at more or less the same position of the prototype compounds [41][42][43][44].…”

Characterization and Catalytic Activity of New Metal‐organic Frameworks Resulted from Self‐assembly of Ph3SnCl, K[Cu(CN)2] and Nitrogen Donor Ligands

“…26 The latter finding reflects the fact that the MOFs 1-5 should not have similar structures in spite of the fact that they have the same chemical formulae as well as their structures are different from that of [Me 3 SnCu(CN) 2 •pyz]. 26 However, the MOFs 1 and 2 seem to be isostructural since they have the same reflections.…”

“…[18][19][20][21][22][23][24][25][26][27] It has been shown that organometallic R 3 E ＋ units (R＝Me, Et, n-propyl, n-butyl, phenyl; E＝Sn, Pb) can bridge the cyanometallate anions, M(CN) n q-, in much the same fashion as silver do in SPB 28 except that the greater complexity of the R 3 E ＋ units leads to complicated three-dimensional polymer. 26,27,[29][30][31] The supramolecular interplay of the Ph 3 Sn ＋ unit and the tetrahedral [Cu(CN) 4 ] 3-ion with either pyz, mepyz, bpy, tbpe, or bpe as bidentate ligands (L) in presence of H 2 O affords the products [(Ph 3 Sn) 3 Cu(CN) 4 •L•XH 2 O]. 27 The water molecules are usually coordinated to tin atoms and are involved in two significant O-H-N hydrogen bonds, wherein the nitrogen atoms belong either to the bidentate ligand or the M-coordinated cyanide ligands.…”

3D-Interpenetrating Frameworks of 3∞[Cu2(CN)4(Me3Pb)2(bpy)] Containing the Rhombic [Cu2(µ3-CN)2] Motifs

“…groups on the topology of the SCP. However, the structure features of these SCP are the formation of 3D-networks which contain the rhombic [Cu 2 (l 3 -CN) 2 ] motif or strong Cu…Cu interaction, even shorter than in elemental copper, via interwoven of the sheets [7][8][9]. Such porous networks have potential applications in areas such as separations, gas storage, antitumor, luminescence and catalysis [5,[10][11][12].…”

“…Pb(Me 3 ) / NC-Cu-]-, which create voluminous 3D-networks wherein one carbon atom of each [CNPb(Me 3 )NC] spacer interacts with a pair of copper ions. The structure of 1 is quite different than that of [CuCN Me 3 SnCN pyz], 2[8]. The basic sub-units of 2 consist of distorted-adamandoid Cu 10 cages whose surfaces are surrounded either by [Cu 6 (pyz)4 {Sn-(NC) 2 } 2 ] or by [Cu 6 (pyz) 2 {Sn(NC) 2 } 4 rings.…”
