Abstract
The crystal structures of the new compounds spiro[1,3-dihydroperimidine-2,9′-fluorene] (1), and co-crystal (2) consists of 1 and 9-fluorenone were obtained by single crystal X-ray diffraction. Compound 1 crystallizes in the orthorhombic space group Pbca, with lattice parameters: a = 14.914(9) Å, b = 16.2126(8) Å, c = 26.4850(14) Å and Z = 16. Co-crystal 2 crystallizes in the orthorhombic space group Pca2(1), with lattice parameters: a = 18.0732(9) Å, b = 7.7216(4) Å, c = 17.8262(9) Å and Z = 4. Details of the synthesis, structures, thermal and spectroscopic properties of the new compounds are discussed.
