AbstractTwo novel sulfido-heterometallic polymers, [(18-crown-6) KAgWS4](n) and [{(18-crown-6)Ba(DMF)(4)}(Ag2W2S8)](n) 2, induced by supramolecular cations, were synthesized through the reaction of 18-crown-6, silver nitrate, ammonium thiotungstate and potassium nitrate or barium nitrate, respectively. Both 1 and 2 were characterized by elemental analyses, IR, UV-vis, H-1 NMR spectra and X-ray single crystal determination. Compound 1 crystallizes in the orthorhombic space group Cmc2(1) with a 14.163(5), b = 15.063(7), c = 10.550(3) Angstrom, Z = 4, d 2.135 g cm(-3), R-1 = 0.0487, wR(2) = 0.1257 (on 1602 observed reflections with I > 2sigma(I)). It has a wave-like one-dimensional anion complex polymer configuration, on which is appended the supramolecular cation, [(18-crown-6)K](+) arrangement. Compound 2 crystallizes in the monoclinic space group P2(1) with a = 8.4524(l), b = 18.0486(l), c = 15.6294(1) Angstrom, beta = 93.299(1)degrees, Z = 4, d = 4.280 g cm(-3), R, = 0.0323, wR(2) = 0.0619 (on 5941 observed reflections with I > 2sigma(I)). It consists of a zigzag sulfido-silver-tungsten anion chain and a [(18-crown-6)Ba(DMF)(4)](2+) ion, in which the barium ion is coordinated by the six oxygen atoms of the crown ether molecule and four oxygen atoms of the DMF molecules.
