Crystal and molecular structures of trans-dibromobis(1,4-oxathian)-platinum(II) and trans-dibromobis(1,4-oxaselenan)platinum(II)

Abstract

The structures of the title compounds have been determined by heavy-atom X-ray methods. Both complexes are monomeric, square-planar platinum(II) compounds. They differ in configuration, the oxathian complex (I) has the Pt–S bond (2.281 Å) equatorial to the ring whereas in the oxaselenan complex (II) the Pt–Se bond (2.430 Å) adopts the axial position. Crystal data : (I), space group P21/n, a= 4.515(5), b= 19.717(10), c= 7.609(5)Å, β= 97.2(2)°, Z= 2; (II), space group P21/c, a= 6.36(1), b= 10.47(2), c= 10.80(2)Å, β= 102.1(1)°, Z= 2. The structures were refined by least-squares methods to R 0.065 [(I), 872 reflections (photographic)] and 0.069 [(II), 596 reflections (diffractometer)].
