%X A novel efflorescent complex of bismuth(III) with ethylene glycol has been synthesized, and its structure determined by single-crystal X-ray diffraction and refined to a residual R 0&#183;055 for 1811 observed reflections. Crystals are triclinic, space group P-1, with two dimers forming the asymmetric unit in a cell with dimensions a 8&#183;885(3), b 10&#183;796(4), c 7&#183;586(3) &#197;, &#945; 93&#183;19(3), &#946; 106&#183;61(3), &#947; 105&#183;72(3)&#176;. The &#91;Bi2(C2H4O2)3&#93; dimer unit, which comprises two different bismuth centres, one five-, the other six-coordinate, is extended into a stable three-dimensional polymer framework via associations through all three ethane-1,2-diolato(2&#8211; ) ligands which are bidentate and, in most cases, bridging. The lattice also contains weakly associated but uncoordinated molecules of hydration which are considered responsible for the crystal instability.
