Abstract

The halogen-bridged transition metal complex [Pt(en)2][PtCl2(en)2](ClO4)4 has a quasi-one dimensional structure with Pt ions forming chains along the b-axis. The valence of the Pt ions can have two possible values, II and IV, and is disordered. Diffuse X-ray scattering was found for wavevectors around (0 2n +1 0). The intensity distribution along the (0 1 0) was very narrow, while that for wavevectors perpendicular to (0 2n +1 0) showed clearly the existence of a short range order between the valence sequences of neighboring chains. A strong correlation has been found between the chain at the origin and one at the second neighbor position along the c-axis. The results were analyzed in terms of interchain interactions.
