摘要: Partially oxidized one-dimensional (1D) Pt−Pt chain compounds [Pt2(MeCS2)4]4ClO4·5PhCN (1) and [Pt2(EtCS2)4]5(ClO4)2 (2) were synthesized by electrocrystallization of diplatinum(II,II) complexes from different solvents. 1 2 consist 1D chains stacked dimers with short interdimer S···S contacts. Depending on the number ClO4− per dimer their positions, forms a regular stack dimers, whereas pentamer in chain. exhibits high electrical conductivity (4.2−8.0 S cm−1) at 300 K metallic behavior above 125 K. is semiconductor. almost temperature independent magnetic susceptibility (ca. 1.1 × 10−4 emu mol−1) which attributed to Pauli paramagnetism, spin degree freedom has been lost. Although basic structures are closely related, they exhibited solid-state properties that depend valence state platinum atoms periodicity within
