Abstract
Diplatinum(II) complex, Pt2(EtCS2)4, is synthesized and characterized by X-ray crystal structure analysis using a synchrotron radiation at SPring-8. The crystal structure consists of diplatinum units stacking in columns along the four-fold axis, with intra and interdimer Pt-Pt distances of 2.764(1) and 3.428 (1) Å, respectively.
