Comment
The title compound was prepared in order to evalute its potential as antibacterial and antifungal agents. The CCDC search (Allen, 2002) showed that the crystal structures of rac-exo-tricarbonyl-(h6-3-phenyl isochromanone)chromium (Schnebel et al., 2003) and 3,4-dihydro-8-hydroxy-3-(4-hydroxyphenyl)isocoumarin (Schmalle et al., 1982) have been reported, which have close resemblance as far as isochromane and attached phenyl ring is considered. We report herein the synthesis and crystal structure of the title compound.
In the molecule of the title compound ( Fig. 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges. In the crystal structure, there is a C-H···π interaction (Table 1).

Refinement
H atoms were positioned geometrically, with C-H = 0.95, 1.00 and 0.99 Å for aromatic, methine and methylene H, respectively, and constrained to ride on their parent atoms, with U iso (H) = 1.2U eq (C).
