摘要
The structure of 2,6-bis(2-pyridyltsulfanylmethyl)pyridine (pytmp), (I), C(17)H(15)N(3)S(2), presents a twisted conformation, with the three planar moieties almost perpendicular to each other. The structures of two related derivatives, namely 2,6-bis(6-methyl-2-pyridylsulfanylmethyl)pyridine (mpytmp), (II), C(19)H(19)N(3)S(2), and 2,6-bis(4-methyl-2-pyrimidylsulfanylmethyl)pyridine (mprtmp) n-pentane hemisolvate, (III), C(17)H(17)N(5)S(2)center dot 0.5C(5)H(12), present extended planar fragments with just one quasi-perpendicular arylsulfanylmethyl side arm, such that the molecules are folded in an L-shaped conformation. All three conformations appear different from those adopted by similar compounds, demonstrating the great flexibility of such species, although such differences in conformational behaviour might drive specific coordination modes.
