Abstract
X-ray absorption near-edge structure (XANES) and extended X-ray absorp tion fine structure (EXAFS) studies on the tetra(n-butyl)ammonium salt of [Ni(dmbit)(2)](x-) (x = 2,1 and 0.29) and [Ni(dmbbip)(2)](-) have been performed in order to reveal the structural parameters of the [Ni S4](x-) core along with the chemical state. The central nickel ion is confirmed to have coordination number four with square-planar geometry . The [Ni-S] bond distance in [Ni(dmbit)(2)](-) (2.154 Angstrom) is id entical with that of [Ni(dmbbip)(2)](-), but shorter than those of [Ni (dmbit)(2)](2-) (2.178 Angstrom) and [Ni(dmbit)(2)](0/29-) (2.165 Angs trom).
