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.
摘要
标题化合物C(36)H(36)N(4)O(4)是通过罗丹明染料的螺内酰胺环形成反应制备的，用于与开环形式进行比较。呫吨环系统近似平面 [呫吨环的平面度均方根偏差 = 0.023 (9) Å]。螺内酰胺环和1,3-苯并二恶唑环与呫吨环系统形成的二面角分别为86.8 (1)°和74.3 (1)°。
