Abstract:The title compound, C35H38N4O3, was prepared as a spirolactam ring formation of rhodamine dye for comparison with a ring-opened form. The xanthene ring system is approximately planar. The dihedral angles formed by the spirolactam and phenol rings with the xanthene ring system are 85.7 and 109.4 degrees, respectively. Each of the molecules in the crystal structure contains one intramolecular O-H center dot center dot center dot N hydrogen bond, and they form intermolecular N-H center dot center dot center dot O hydrogen-bonded chains along the [100] direction. Weak intermolecular C-H center dot center dot center dot O hydrogen-bonding contacts connect the infinite chains via crystallographic inversion centres to form a two-dimensional network.
