The dimer of 1-indanolyl obtained from the UV photolysis of 1-indanone
in 2-propanol is trans-alpha,alpha'-biindanyl-alpha,alpha'-diol, (C9H
9O)(2). There are two almost identical molecules in the asymmetric uni
t linked by a hydrogen-bonding system that extends along the a axis. B
ond distances and angles are as expected.
