Synthesis and Crystal Structures of Four Cyanide‐Bridged Coordination Polymers

Abstract

The hydrothermal reaction of Cu(NO3)2·3 H2O, K3Fe(CN)6, and 1,10‐phenanthroline (1,10‐phen) or 2,2'‐bipyridine (2,2'‐bpy) gives rise to the three one‐dimensional helical‐chain complexes [Cu2Fe(CN)4(1,10‐phen)3]n·0.5n H2O (1), [Cu3(CN)3(1,10‐phen)3]n (2), and [Cu3(CN)3(2,2'‐bpy)3]n (3), and the two‐dimensional layer complex [Cu3Fe(CN)5(2,2'‐bpy)2]n (4). The structure of 1 contains a cyanide‐bridged CuI···FeII···CuI chain in which the two copper and one iron centers exhibit different coordination environments. The structures of 2 and 3 are both monometallic. Complex 4 is constructed alternately from fused 6‐ and 14‐metal‐membered nonplanar centrosymmetric rings that form a 2D layer architecture.

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

“…To date, quite a few single-or double-helical chains have been generated [7][8][9][10][11][12][13], with most helical polymers being obtained by using chiral ligands [14][15][16] or oligo-pyridines [17] and other optically active ligands [18,19]. In addition, the design and synthesis of novel coordination architectures can be controlled by varying the reaction conditions, including temperature [20], metal-to-ligand ratio [21], pH value [22], solvents [23], and counter anions [24].…”

Self-assembly and antitumor activity of an organotin coordination polymer containing a helical structure based on copper cyanide and phenanthroline ligand

“…Helical structures have received special attention due to their potential applications in asymmetric catalysis, bioactivity, and nonlinear optical materials [32]. To date, some single-or double-helical chains have been generated [33][34][35][36][37][38][39][40] with most helical polymers being obtained by using chiral ligands [41][42][43][44] or oligo-pyridines and other optically active ligands.…”

Hydrothermal synthesis and crystal structure of a novel cyanide-bridged double helical copper(I) coordination polymer [Cu3(CN)3(phen)]

“…One third of cyanides coordinate to Cu(I) atoms through N end of (phen)Cu-CN-side-arms to form the interchain bridges. Recently the construction of helical coordination polymers has aroused much attention [18,19], and quite a few single helical copper(I) cyanide chains incorporating organodiimine or N-heterocyclic ligands have been reported [12,13]. To our knowledge, the complex 1 is the first example of cyanide-bridged copper(I) coordination polymer with double helical framework.…”

“…This p-p interaction plays an important stable role in constructing the crystal structure of complex 1. (12). Symmetry #1 x, y, z À 1; #2Àx + 1, Ày + 1, Àz; #3À x, Ày + 1, Àz; #4 x, y, z + 1.…”

“…Transition metal cyanides have been studied extensively over the past two decades due to their great importance in magnetism and other properties [3,4], but recent work focuses on copper(I) cyanide system because of the known versatility of [Cu(CN)] n structural motifs in accommodating various ligands, and Cu(I) compounds have rich fluorescent properties [5][6][7][8][9]. Colacio and Lu with co-workers have been investigating a series of copper(I) cyanide coordination polymers incorporating diamine, organodiimine and N-heterocyclic ligands [10][11][12][13].…”
