摘要：

The reaction between 1-phenyl-tetrazole-5-thione ( 1) and the metal hydroxides MOH (M = Li, Na, K, Rb, Cs) in the presence of crown ethers led to the alkali metal complexes, [Li(15-crown-5)(SCN4Ph)] (2), [Na (15-crown-5)(SCN4Ph)] (5), [K(18-crown-6)(SCN4Ph)] (4), [Rb(18-crown-6)(SCN4Ph)] (5), [Cs(15-crown-5) 2][SCN4Ph] (6), [{Cs(15-crown-5)(SCN4Ph)}] (6a), [Cs(18-crown-6)(SCN4Ph)] (7), [Cs(dibenzo-24-crown-8)(SCN4Ph)] (8) and [Cs-2(dibenzo-24-crown-8)(3)(SCN4Ph)(2)] (8a). Compounds 2-8 were characterized by physical and analytical methods. X- ray diffraction studies performed on these compounds reveal that crown ether moiety precludes the ionic lattice formation. The tetrazole anion coordinates to the metal cation in a bidentate N, S fashion in 3-5 with the formation of a four- membered MSCN ring, whereas in 2, monodentate coordination through a N atom is observed. In contrast, cesium complexes 6, 6a, 7, 8 and 8a show a variety of structural arrangements including monomeric, dimeric and polymeric species, depending on the size of crown ether employed.
