2-[(2,4-Dihydroxy-benzyl-idene)amino]-3',6'-bis-(ethyl-amino)spiro-[isoindoline-1,9'-xanthen]-3-one.

ABSTRACT: The title compound, C(35)H(36)N(4)O(4), was prepared as a spiro-lactam ring formation of rhodamine B dye for comparison with a ring-opened form. The xanthene ring system is approximately planar. The r.m.s. deviation from planarity is 0.064 (6) Å for the xanthene ring. The dihedral angles formed by the spiro-lactam and 2,4-dihydroxy-benzene rings with the xanthene ring system are 86.6 (9) and 88.0 (9)°, respectively.
