The dithio-carbamate anions in the title compound, [Ni(C(7)H(14)NS(2))(2)], chelate to the Ni(II) atom, which is four-coordinate in a square-planar geometry. The Ni(II) atom lies on a center of inversion.

In the title compound, [Zn(C(8)H(16)NS(2))(2)], the Zn(II) atom is chelated by two S,S'-bidentate dithio-carbamate ions in a very distorted tetra-hedral geometry. The alkyl chains of the ligands are equally disordered over two sets of sites.

The administration of adenosine together with homocysteine resulted in a dose-related elevation of cerebral S-adenosyl-Lhomocysteine without concomitant perturbation of S-adenosyl-Lmethionine levels. The adenosine + homocysteine treatment also decreased the incorporation of labjle and stable methyl groups into brain protrjins. Brain [ HI-phosphatidyl N,N-dimethylethanolamine and [ HI-phgsphatid...

The dithio-carbamate anions in the title compound, [Sn(C(6)H(5))(2)(C(5)H(10)NS(2))(2)], chelate to the Sn(IV) atom, which is six-coordinated in a skew-trapezoidal-bipyramidal geometry. The mol-ecule lies across a twofold rotation axis.

In this paper, we prove that there exist infmitely many positive integers n satisfying S(Z(n»> Z(S(n» or S(Z(n» < Z(S(n».
