In this paper, we show that the necessary and sufficient condition for the existence of an e S k-factorization of (Cm • Kn) * is n ≡ 0 (mod k(k − 1)), for all m > 3. In fact, our result together with a result of Ushio gives a complete solution for the existence of an e S k-factorization of (Cm • Kn) * for all m ≥ 3. Further, we have obtained some necessary… (More)
In the crystal structure of the title compound, C(8)H(11)N(2)S(+)·NO(3) (-), cations and anions are linked by inter-molecular N-H⋯O hydrogen bonds, forming one-dimensional chains along .
The asymmetric unit of the title compound, (C(8)H(11)N(2)S)(2)[ZnCl(4)], contains two S-benzyl-isothio-uronium cations which differ in the C-C-S-C torsion angle [165.3 (2) and 81.9 (2)°] and a tetrahedral tetra-chloridozincate anion. The crystal structure is stabilized by N-H⋯Cl, C-H⋯Cl and C-H⋯S inter-actions.
