Title
Electron Microscopy and Magnetic Properties of Tetra(n-butyl)ammonium salts of [Ni(dmbit)2]1- and [Ni(dmbbip)2]1- (dmbit2-:C7H2S5:2-thiobenzo[d]-1,3-dithiole-5,6-dithiolate;dmbbip2-:C12H16S4:1,2-bis(isopropylthio)benzene-4,5-dithiolate)

Abstract
Monoanionic nickel(Ⅲ) complexes, [Ni(dmbit)2]1- and [Ni(dmbbip)2]1- where dmbit2- and dmbbip2- denote 2-thiobenzo[d]-1,3-dithiole-5,6-dithiolate and 1,2-bis(isopropylthio)benzen-4,5-dithiolate, respectively, have been synthesized by the iodine oxidation of dianionic complexes. In the scanning electron microscopic(SEM) images, these complexes show the well-grown two-dimensional layered structures which are clearly comparable to the dianionic ones with three-dimensional structures. Magnetic susceptibilities of nickel(Ⅲ )complexes are fitted well with the two-dimensional Heisenberg antiferromagnet model of S=1/2 system resulting in the spin-exchange parameters (
