The asymmetric unit of the title compound, (C(14)H(17)N(2)S(2))[Ru(C(10)H(14))Cl(3)], contains a 1,3-bis-(thio-phen-2-ylmeth-yl)-3,4,5,6-tetra-hydro-pyrimidinium cation and a trichlorido(η(6)-p-cymene)ruthenate(II) anion. The Ru atom exhibits a distorted octa-hedral coordination with the benzene ring of the p-cymene ligand formally occupying three sites and three chloride atoms occupying the ot...

The phytotoxicity of the three major monoterpene constituents of the essential oil from leaves of Artemisia scoparia Waldst. & Kit. (redstem wormwood) was investigated. GC/GC-MS analysis revealed that the essential oil (yield 0.84%) is a complex mixture containing 19 monoterpenes, 7 sesquiterpenes and 15 other compounds--aliphatic alcohols, ketones, aromatic hydrocarbons and esters. The three m...
