<jats:p> [Pt(dapn)<jats:sub>2</jats:sub>]Br<jats:sub>3</jats:sub> (dapn = 1,2-diaminopropane), ortho-rhombic, Immm (D<jats:sup>25</jats:sup>
<jats:sub>2h</jats:sub>), a = 5.338(1), b = 6.900(5), c= 19.738(4) Å, Z = 2, V= 727 Å<jats:sup>3</jats:sup> , d<jats:sub>c</jats:sub> = 2.7 g · cm<jats:sup>-3</jats:sup> . The structure was refined to R = 0.094 for 576 reflections and can be described as a Wolffram's salt analogue. A rotating crystal photograph shows weak diffuse layers between the Bragg reflections as evidence for one-dimensional order along the M-X-M chain, but for successful refinement the M-X distance (2.673(1) Å) have to be assumed to be equal.</jats:p>
