A new benzothiazoline was prepared from the chiral aldehyde (1R)-(－) - myrtenal. The reaction of the benzothiazoline with [Pt(hfacac)2] in toluene afforded the sulfur-bridged tetranuclear platinum(II) complex 1. The molecular structure of 1 was determined by the single-crystal X-ray diffraction method. Crystal data were as follows: a = b = c = 18.473(5) Å, V = 6308(3) Å3, space group = P43, Z = 4. On the other hand, a similar reaction in methanol led to the deep blue complex 2, which was characterized by absorption and 1H NMR spectra, the results suggesting that 2 has an electronic structure of semiquinone form.
