The title compound, [Ag(L)]·H2O, 1, where HL=4-(isonicotinamido)benzoic acid, was synthesized in methanol solution and its crystal structure was determined by X-ray diffraction analysis. The crystal is of monoclinic, space group P21/c with a=0.571 8(8) nm, b=1.357 2(18) nm, c=1.558 0(2) nm, β=91.090(2)°, V=1.209 0(3) nm3, Z=4, Dc=2.009 g·cm-3, F(000)=722, Rint=0.042 9, R=0.027 1, wR=0.055 6. In complex 1, the Ag atoms are linearly coordinated by one O atom and one N atom of two ligand molecules. Each L-ligand in turn uses its one carboxylate group and one pyridinyl groups to connect two metal centers, then the one-dimensional (1D) chains is formed. On the other hand, the 1D chains are further connected by O1W-H1WB…O2 hydrogen bonds and Ag-O weak interactions to give a two-dimensional (2D) layer, finally, the 2D net extents to three-dimensional (3D) supramolecular framework by O1W-H1WB…O1 as well as N2-H2…O2 interactions.
The title compound,[Ag4(L)4](PMBS)4·2H2O (1),where L=2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene,PMBS =p-methylbenzenesulfonate was synthesized and its crystal structure was determined by X-ray diffraction structure analysis. The crystal is of triclinic,space group P1 with a=0.820 3(2) nm,b=1.322 7(3) nm,c=2.061 0(3) nm,α=76.155(2)°,β=78.651(4)°,γ=89.993(3)°,V=2.126 2(8) nm3,Z=2,Dc=1.644 g·cm-3,F(000)=1 068,R=0.052 4,wR=0.113 6. The Ag atoms are linear coordinated by two N atoms of two L ligands,while the p-methylben-zenesulfonate molecules are included in the lattice and connected to [Ag(L)]n by hydrogen bonding interactions to form a three-dimensional supramolecular structure.
