Treatment of [Cu(CH3CN)4]+ with 2-(4-dimethylaminophenyl)benzothiazoline in the presence of halide ions (X = Cl−, Br−, and I−) gave [Cu16L12X]3+ (L = (C6H4NMe2)CH=N(C6H4)S−) with a spherical Cu16S12 structure, while similar treatment in the absence of halide ions afforded [Cu8L8]2+ with a cyclic Cu8S8 structure.
Thiolato-bridged Au<sup>I</sup><sub>2</sub>Cu<sup>I</sup><sub>2</sub> and Cu<sup>I</sup><sub>4</sub> Metallorings Derived from Benzothiazoline: Can Gold(I) Plus Copper(I) Make Silver(I)?
A thiolato-bridged AuI2CuI2 metalloring compound, [Au2Cu2(L)4] (L = (C6H4NMe2)CH=N(C6H4)S−), together with an analogous CuI4 compound, [Cu4(L)4], was newly prepared from 2-(4-dimethylaminophenyl)benzothiazoline. The AuI2CuI2 compound was found to show structural and spectroscopic features comparable well with those of [Ag4(L)4], rather than those of [Au4(L)4] and [Cu4(L)4].
Certain chemical analogs and related compounds useful in the control nematodes that infest plants or the situs of plants are described. Nematodes that parasitize animals can also be controlled using the methods and compounds of this invention.
