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) ? b = 93...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) ? b = 93.l16(l)? V = 4297.3 ?, Z = 4, Dc = 1.448 g/cm3, m = 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, 3/2y, 1/2+z).展开更多
A new cluster-cracking method to synthesize dithiolate metal complexes was reported and four unsymmetric complexes with formula (Me4N)(2)[M(Ln)(SPh)(2)] (M = Cd and Zn, L1 = dmit = 1, 3-dithiole-2-thione-4, 5-dithiola...A new cluster-cracking method to synthesize dithiolate metal complexes was reported and four unsymmetric complexes with formula (Me4N)(2)[M(Ln)(SPh)(2)] (M = Cd and Zn, L1 = dmit = 1, 3-dithiole-2-thione-4, 5-dithiolate, L2 = dmid = 1, 3-dithiole-2-one-4, 5-dithiolate, SPh = thiophenolate) (1-4) were characterized by, elemental analysis, ER, UV NMR spectra and so on. The advantages of this method am summarized in two aspects: (1) the preparation is very convenient; (2) the reaction usually completed giving the product with high,purity. The crystal structure of 1 showed that the bond distances of Cd(II) to the sulfur of the thiophenolate group are shorter than those of Cd(II) to the sulfur of dmit, so that the thiophenolate group does not be replaced in the reaction and the mixed ligand complexes are the dominant products. The dmit complexes showed well third-order NLO properties, but not of the dmid complexes, although druid is an analogue to dmit.展开更多

The most intriguing general structural feature of the compound is the completely segregated columnar stacks of anions and cations. There exist hydrogen-bonding interactions within the cation column.展开更多
