• The molecular structure of an anhydrous zinc 8-quinolinolate obtained by sublimation has been determined by means of X-ray diffraction. The complex forms triclinic crystals; <I>a</I>=11.858(1), <I>b</I>=13.019(2), <I>c</I>=10.834(1) Å, α=106.56(1), β=109.00(1), and γ=74.14(1)°, space group P\bar1 (No. 2) with one [Zn(C<SUB>9</SUB>H<SUB>6</SUB>NO)<SUB>2</SUB>]<SUB>4</SUB> molecule. The structure was solved by the heavy atom method and refined by the block-diagonal least-squares procedure to <I>R</I>=0.043 for 3320 non-zero reflections. The molecule is centrosymmetric and tetrameric; four [Zn(C<SUB>9</SUB>H<SUB>6</SUB>NO)<SUB>2</SUB>] units being connected by oxygen atoms of 8-quinolinolate ligands. Two types of bridging oxygen atoms were found. Two crystallographically independent zinc atoms take different geometries, hexa-, and pentacoordinations.
