N2  - Hydrated scandium(III) picrate has been crystallized in association with excess picric acid to give a 1:1 adduct as material sufficiently substantial to allow single-crystal X-ray structural characterization at c. 295 K. [Sc( pic )2(OH2)4]( pic )( Hpic ).~8.2H2O is monoclinic, P 21/c, a 16.304(9), b 20.061(6), c 14.587(9) &#506;, &#946; 112.98(5)&#176;, Z = 4; R was 0.078 for 2632 reflections [I > 3&#963;(I)]. The scandium is six-coordinate, the coordination sphere comprising a trans pair of phenolic picrate oxygen atoms [Sc-O, 2.019(8), 2.046(8) &#506;; Sc-O-C, 147.6(9), 147.7(9)&#176;] and four water molecule oxygens at appreciably longer distances [Sc-O, 2.100(9)-2.121(8)&#506;].
