One-pot reactions between Ni(II), Pd(II) or Pt(II) salts and 3,6-dichloro-1,2-benzenedithiol (HSC6H2Cl2SH) in KOH medium under argon lead to a series of bis-dithiolene coordination polymers. X-ray analysis shows the presence of a common square planar complex [M(SC6H2Cl2S)(2)](2-) linked to potassium cations forming either a two-dimensional coordination polymer network for {[K-2(mu-H2O)(2)(mu-thf)(thf)(2)][M(SC6H2Cl2S)(2)]}(n) [M = Ni (1) and Pd (2)] or a one-dimensional coordination polymer for {[K-2(mu-H2O)(2)(thf)(6)][Pt(SC6H2Cl2S)2]}(n) (3). In 3 the coordination environment of the potassium ions may slightly change leading to the two-dimensional coordination polymer {[K-2(mu-H2O)(mu-thf)(2)][Pt(SC6H2Cl2S)(2)]}(n) (4) that crystallizes together with 3. The physical characterization of compounds 1-3 show similar trends, they are diamagnetic and behave as semiconductors.
