| Abstract: | Two - dimensional (2D) coordination polymers of L( L = N,N - (2 - pyridyl) - (4 - pyridylmethyl) amine), with empirical formulas -Ag(L)2ClO4], were prepared by hydro(solvo)thermal reactions of L and AgClO4 in mixtures of water and ethanol. Single crystal X- ray diffraction studies reveal that L ligand bridges two argentum centers with both the 4 - pyridyl and 2 - pyridyl nitrogen atoms to result in 2D rhombohedral polymeric grids. The two rings of L are essentially perpendicular to each other, likely to accommodate the coordination of both pyridyl nitrogen atoms to the Ag centers as well as the "intramolecular" hydrogen bonds. Crystal data : monoclinic space group C2/c, a = 0. 848 31(6) nm, b=1.725 4(1) nm, c = 1. 669 9(1) nm, β= 99. 677(6)? V = 2. 559 4(1) nm3. |
