Synthesis and Crystal Structure of 2-dapp2Zn(dmit)2 (2-dapp = 2-(4-Dimethylaminophenyl)ethyl-l-methyl- pyridinium,dmit = 1,3-Dithiole-2-thione-4,5-dithiolato)

摘要

The title compound [2-dapp]2[Zn(dmit)2] synthesized by the direct reaction of [Et4N]2[Zn(dmit)2] and [2-dapp]I crystallizes in monoclinic, space group P2l/c with a = 29.7436(6), b = l0.6266(3), c = l3.6161(4)A,β= 93.l16(l)°, V = 4297.3 A3, Z = 4, Dc = 1.448 g/cm3,μ= 1.091 mm-1 and F(000) = 1936. The structure was refined by fu1l-matrix 1east-squares methods to the final R = 0.075 and wR = 0.l16, revealing the zinc-bis (dmit) anions interact strongly with the planar cation, 2-dapp+, by the hydrogen bond C(l)-H(lC)…S(7) (x, 3/2-y, -1/2+z).
