Abstract
Mex [Pt(CN)4]y nH2O (Me = Sr, Ca, Ba, Mg, Lu, ...)-type crystals show highly anisotropic properties. The strong binding between the CN-ligands and the Pt2+-ion of the [pt(CN)4]2--complex-molecule is well preserved in the crystal (1). This is the reason for the demixing of Pt-d3-electrons (Ham-effect) and, additionally, there is formed a nearly one-dimensional dz2-valence-band for the Pt-Pt-binding within the crystal.
