The title compound crystallizes in monoclinic form, space group P2<SUB>1</SUB>/c with <I>a</I>=20.810(1), <I>b</I>=16.000(1), <I>c</I>=18.131(1) Å, β=107.77(1)°, <I>Z</I>=8. The structure was established by the direct method and refined including all hydrogen atoms by the blockdiagonal least-squares procedure, <I>R</I>=0.062 for 4609 observed reflections. The heterocyclic spiran skeletons in two independent molecules have the same structure; however, four phenyl rings out of five take different conformations to the hetero rings to which they attached.
