ABSTRACT: The title compound, C(36)H(36)N(4)O(4), was prepared as a spiro-lactam ring formation of the rhodamine dye for comparison with a ring-opened form. The xanthene ring system is approximately planar [r.m.s. deviations from planarity = 0.023?(9)?Å for the xanthene ring]. The dihedral angles formed by the spiro-lactam and 1,3-benzodioxole rings with the xanthene ring system are 86.8?(1) and 74.3?(1)°, respectively.

Project description:The title compound, C(35)H(38)N(4)O(3), was prepared as a spiro-lactam 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 spiro-lactam and phenol rings with the xanthene ring system are 85.7 and 109.4°, respectively. Each of the mol-ecules in the crystal structure contains one intra-molecular O-H?N hydrogen bond, and they form inter-molecular N-H?O hydrogen-bonded chains along the [100] direction. Weak inter-molecular C-H?O hydrogen-bonding contacts connect the infinite chains via crystallographic inversion centres to form a two-dimensional network.
