Structural characterization of several cadmium halides with N-donor ligands

Investigation of the crystal structure and electrochemical properties of catena-poly[[chlorido(piperazin-1-ium–κN))cadmium(II)]-di-μ-chlorido]monohydrate

“…The pipiperazin-1-ium, with one unprotonated N atom, is a connector monodendate ligand which adopts a stable chair conformation, with puckering variables: Q T = 0.570(3) Å , h = 179.8(3)°, and u = 180(9)° [25]. The interatomic C-C and C-N distances, ranging from 1.475(2) to 1.518(4) Å , are comparable with those observed in other complexes [26,27], in which the piperazine is an unprotonated ligand which connects CdCl 2 groups to 2D or 3D networks. In the structure of the compound, the CdCl 3 (C 4 H 11 N 2 ) group constitutes the monomeric motif which generates an infinite 1D chain parallel to the a direction (Fig.…”

Syntheses, structures, and properties of two binuclear cadmium(II) iodides containing a bis(tridentate) Schiff base/tetradentate tripodal amine: control of coordination numbers by varying ligand matrices

“…7). Yu et al [7] have reported an iodo-bridged heterodinuclear compound in combination with 1,10-phenanthroline, which contains a trigonal bipyramidal (tbp) copper(II) and a tetrahedral (T d ) cadmium(II) centers linked by the halide. In our present work using the tripodal amine (L2), an iodo-bridged homodinuclear compound is isolated which comprised two cadmium(II) centers-with one tbp geometry and the other with T d environment.…”

“…Research on design and synthesis [1][2][3] of mono-, bi-, and polynuclear coordination compounds of cadmium(II) [4][5][6][7][8][9][10] continues unabated for the preparation of functional materials [11][12][13][14][15] with interesting electronic and optoelectronic properties [15][16][17][18]. Exploiting the diversity in coordination environments around this 4d 10 ion, different metal-organic frameworks [19][20][21] may be accessed using a variety of organic coligands along with different inorganic/organic bridges.…”

Halide-bridged polymers of divalent metals with donor ligands – structures and properties

“…Fig. 11 shows a zig-zag chain in [CdBr 2 (2,2 -bipy)] [83,84]. This family also comprises the not strictly isomorphous but chemically related compounds [CuCl 2 (2,2 -bipy)] [86], [CuBr 2 (4,4 -dimethyl-2,2 -bipy)] [87,88], and the phenanthroline derivatives [CdI 2 (1,10-phen)] [89] and [FeCl 2 (1,10-phen)] [90].…”
