摘要

The title compound, catena-poly[[[bis(ethylenediamine-κ2N,N′)platinum(II)]- μ-chlorido-[bis(ethylenediamine)platinum(IV)]-μ-chlorido] tetrakis{4-[(4-hydroxyphenyl)diazenyl]benzenesulfonate} dihydrate], {[PtIIPtIVCl2(C2H8N2)4](HOC6H4N=NC6H4SO3)4·2H2O}n, has a linear chain structure composed of square-planar [Pt(en)2]2+ (en is ethylenediamine) and elongated octahedral trans-[PtCl2(en)2]2+ cations stacked alternately, bridged by Cl atoms, along the b axis. The Pt atoms are located on an inversion centre, while the Cl atoms are disordered over two sites and form a zigzag ...Cl—PtIV—Cl...PtII... chain, with a PtIV—Cl bond length of 2.3140?(14)??, an interatomic PtII...Cl distance of 3.5969?(15)?? and a PtIV—Cl...PtII angle of 170.66?(6)°. The structural parameter indicating the mixed-valence state of the Pt atom, expressed by δ = (PtIV—Cl)/(PtII...Cl), is 0.643.
