Enantiomerically pure trans-2,3-tetralindiol [(R,R)- or (S,S)-trans-1,
2,3, 4-tetrahydro-2, 3-naphthalenediol, C10H12O2] crystallizes in a la
yered structure, with two independent molecules in the asymmetric unit
and an unbalanced arrangement of hydrogen bonds. The hydroxyl groups
of one molecule form normal, if somewhat long, hydrogen bonds, but one
of the O atoms in the other molecule accepts two protons while the se
cond accepts none. The four O ... O distances range from 2.817(3) to 2
.921 (3) Angstrom.
