摘要分离出了一种新的含非卤素桥接配体的单维铂混价配合物，即链链-聚[[双（乙烷-1,2-二胺-κ 2n，N ‘）铂（II）]-μ-硫氰酸酯-κ 2s:S-[双（乙烷-1,2-二胺-κ 2n，N ’）铂（IV）]-μ-硫氰酸酯-κ 2s:S]四元（高氯酸盐），{[Pt2(SCN)2(C2H8N2)4](ClO4)4} N。PtII和PtIV原子位于反转中心并交替堆叠，由硫氰酸盐配体的S原子连接，形成无限一维链。PtIV-S和PtII⋯S的距离分别为2.3933（10）和3.4705 （10）Å， PtIV-S⋯PtII的角度为171.97(4)°。在该配合物中引入非卤素原子作为桥接配体，扩展了在一维混价配合物中控制电荷密度波（CDW）状态振幅的化学修饰可能性。分离的PtIV硫氰酸酯化合物(his（乙烷-1,2-二胺-κ2N，N '） his (thiocyanato-κS)platinum(IV) his（高氯酸盐）1.5-hydrate, [Pt(SCN)2（C4H8N2)2](ClO4)2·1.5H2O）具有单斜（C2）对称性。两个s键硫氰酸酯配体位于反位，S-Pt-S角为177.56(3)°。
A new one-dimensional platinum mixed-valence complex with nonhalogen bridging ligands, namely catena-poly[[[bis(ethane-1,2-diamine-κ2N,N′)platinum(II)]-μ-thiocyanato-κ2S:S-[bis(ethane-1,2-diamine-κ2N,N′)platinum(IV)]-μ-thiocyanato-κ2S:S] tetrakis(perchlorate)], {[Pt2(SCN)2(C2H8N2)4](ClO4)4}n, has been isolated. The PtII and PtIV atoms are located on centres of inversion and are stacked alternately, linked by the S atoms of the thiocyanate ligands, forming an infinite one-dimensional chain. The PtIV—S and PtII⋯S distances are 2.3933 (10) and 3.4705 (10) Å, respectively, and the PtIV—S⋯PtII angle is 171.97 (4)°. The introduction of nonhalogen atoms as bridging ligands in this complex extends the chemical modifications possible for controlling the amplitude of the charge-density wave (CDW) state in one-dimensional mixed-valence complexes. The structure of a discrete PtIV thiocyanate compound, bis(ethane-1,2-diamine-κ2N,N′)bis(thiocyanato-κS)platinum(IV) bis(perchlorate) 1.5-hydrate, [Pt(SCN)2(C4H8N2)2](ClO4)2·1.5H2O, has monoclinic (C2) symmetry. Two S-bound thiocyanate ligands are located in trans positions, with an S—Pt—S angle of 177.56 (3)°.
