The mols. of the title compd. are assocd. as dimers by H bonds H(1)-O(2)'. Addnl. characteristic atom distances of the dimer: O(1)-O(2)' 2.650(3) (intermol.), H(1)-O(2)' 1.74 (intermol.), O(1)-H(1) 0.91, C(10)-O(2) 1.225(4) and C(10)-O(1) 1.293(3) .ANG.. The C(10)-O(2) bond distance is slightly longer than the std. distance range for such dimers of 1.205 to 1.215 .ANG. whereas the C(10)-O(1) bond distance is slightly shorter than the std. distance of 1.308 .ANG.. Crystallog. data and at. coordinates are given.
