Crystals of trans-Pt(2)(mu-X)(2)X(2)(CO)(2) (X = Br, I) have been grown and their molecular and crystalline structures have been solved by X-ray diffraction methods. In both cases the dinuclear molecules are bent, with a bending angle of 164.6 degrees and 156.5 degrees for the bromide and the iodide, respectively. While the structure of the bromo-derivative is reported here for the first time, a modification of trans-Pt(2)(mu-I)(2)I(2)(CO)(2) with planar centrosymmetric molecules is known.

Abstract
Crystals of trans-Pt(2)(mu-X)(2)X(2)(CO)(2) (X = Br, I) have been grown and their molecular and crystalline structures have been solved by X-ray diffraction methods. In both cases the dinuclear molecules are bent, with a bending angle of 164.6 degrees and 156.5 degrees for the bromide and the iodide, respectively. While the structure of the bromo-derivative is reported here for the first time, a modification of trans-Pt(2)(mu-I)(2)I(2)(CO)(2) with planar centrosymmetric molecules is known. This appears to be a rare case of a platinum(II) halo-bridged derivative structurally characterized in both bent and planar forms.File in questo prodotto:
