Characterization of a Novel CuII/4, 4'-Bipyridine Coordination Polymer Containing Square Grids

TLDR: In an attempt to obtain new square grid polymers we could prepare the copper(II) complex [Cu(4, 4'-bipy)2 (H2O)2 ] by single crystal X-ray diffraction methods as mentioned in this paper, which is a square grid polymer with the saccharinate anions sandwiched between the complex layers and the DMF molecules filling the square holes.

Abstract: In an attempt to obtain new square grid polymers we could prepare the copper(II) complex [Cu(4, 4'-bipy)2 (H2O)2](sac)2 · DMF (4, 4'-bipy = 4, 4'-bipyridine; sac = anion of saccharin; DMF = dimethylformamide) Its structure was determined by single crystal X-ray diffraction methods It crystallizes in the orthorhombic space group Pcnb (a = 144994(2), b = 158128(3), c = 166850(2) A, Z = 4) and is a square grid polymer with the saccharinate anions sandwiched between the complex layers and the DMF molecules filling the square holes UV-vis, diffuse reflectance and IR spectra, room temperature magnetic susceptibility and the thermal behaviour were also investigated Charakterisierung eines neuartigen, viereckige Gitter enthaltenden CuII/4, 4'-Bipyridin Koordinationspolymer Bei Versuchen neue viereckige Gitter-Polymere zu erhalten, gelang es den Kupfer(II)-Komplex [Cu(4, 4'-bipy)2(H2O)2] (sac)2 · DMF (4, 4'-bipy = 4, 4'-Bipyridin; sac = Anion des Saccharins; DMF = Dimethylformamid) darzustellen Seine Struktur wurde rontgenographisch an Einkristallen bestimmt Er kristallisiert in der orthorhombischen Raumgruppe Pcnb (a = 144994(2), b = 158128(3), c = 166850(2) A, Z = 4) und bildet ein viereckiges Polymer-Gitter mit den Saccharinat-Anionen zwischen den Komplex-Schichten und mit den DMF-Molekulen in viereckigen Lucken UV-vis-, Reflexions- und IR-Spektren, sowie die magnetische Suszeptibilitat (bei Raumtemperatur) und das thermische Verhalten, wurden auch untersucht
