Abstract

The crystal structures of the title compounds [Hg{Mo(CO)3(C5H5)}2] (1) and [IHg{Mo(CO)2-(C5H4Me)(AsPhMe2)}] (2) have been determined by X-ray diffraction at 295 K and refined by least squares to residuals of 0.065 and 0.079 for 867 and 1313 ‘observed’ reflections respectively. [Hg{Mo(CO)3(C5H5)}2] is monoclinic, C2/c, a = 21.161(5), b = 7.106(1), c = 12.103(2) Å, β = 91.23(2)°, Z = 4. [IHg{Mo(CO)2(C5H4Me)(AsPhMe2)}] is monoclinic, P21/a, a = 24.784(8), b = 7.751(3), c = 9.949(3) Å,β = 105.16(3)°, Z = 4. The molecule in (1) has symmetry 2. Coordination about the mercury is substantially linear in both cases: (1) Mo-Hg-Mo 173.71(6)°, Hg-Mo 2.746(2) Å, (2) Mo-Hg-I 167.40(8)°, Hg-Mo 2.685(3), Hg-I 2.720(3), Mo-As 2.536(4) Å.
