2-(2-Hy-droxy-phen-yl)-3,4-dihydro-iso-quinolin-1(2H)-one.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(13)NO(2), in both the six-membered dihydro-pyridine rings adopt a half-chair conformation. The two benzene rings make dihedral angles of 43.66†(10) and 62.22†(10)° in the two mol-ecules. In the crystal, the two independent mol-ecules are linked alternately by inter-molecular O-H⋯O hydrogen bonds, forming a zigzag chain along the c axis. Furthermore, inter-molecular C-H⋯π inter-actions link the chains into a three-dimensional network.
