Two new coordination polymers of saccharinato-silver(I) complexes with 2-pyridylmethanol (mpy) and 2,6-pyridinedimethanol (dmpy), [Ag(sac)(mu-mpy)](n) (1) and [Ag(mu-sac)(dmpy)](n) (2), (sac = saccharinate), have been synthesized and structurally characterized by elemental analysis, IR, thermal analysis and single crystal X-ray diffraction. Crystal data: 1, monoclinic, P2(1)/c, with a = 13.3584(14) b = 8.3040(10) c = 13.0430(14) angstrom, beta = 106.227(3)degrees, Z = 4; 2, monoclinic, P2(1)/n, with a = 7.3538(1) angstrom, b = 13.0444(3) c = 15.7315(3) angstrom, beta 98.8976(13)degrees, Z = 4. In 1, [Ag-2(sac)(2)(mpy)(2)] building blocks are connected into a two-dimensional framework by bridging OH groups of mpy, and they are further stacked by O-(HO)-O-... hydrogen bonds, and weak pi(sac)(...)pi(py) and pi(py)(...)pi(py) interactions to form a three-dimensional supramolecular framework. In 2, [Ag-2(sac)(dmpy)] units are linked by the O-sulfonyl bridges of sac, leading to one-dimensional polymeric chains, which are reinforced by the O-(HO)-O-... hydrogen bonds and pi(sac)(...)pi(py) interactions to generate a three-dimensional supramolecular network. The coordination polymers 1 and 2 exhibit three- and four-coordinated silver(I) centers, respectively, and the intra-chain (AgAg)-Ag-... separations in 1 and 2 are 3.2988(4) and 4.1429(2) angstrom, respectively.
