Di-tert-butyl 2,2′-[9H-fluorene-9,9-diylbis(p-phenyl­ene­oxy)]diacetate

In the title mol­ecule, C(37)H(38)O(6), the non-fused C atom belonging to the five-membered ring of the fluorene system is connected to two p-phenyl­ene rings, the rings opening up the C(ar­yl)–C—C(ar­yl) angle to 113.1 (1)°. The four-atom –O–CH(2)–C(=O)–O– chain between the p-phenyl­ene ring and th...

description In the title mol­ecule, C(37)H(38)O(6), the non-fused C atom belonging to the five-membered ring of the fluorene system is connected to two p-phenyl­ene rings, the rings opening up the C(ar­yl)–C—C(ar­yl) angle to 113.1 (1)°. The four-atom –O–CH(2)–C(=O)–O– chain between the p-phenyl­ene ring and the tert-butyl group assumes a more regular W-shaped conformation for one substituent [O—C—C—C torsion angle = 171.9 (2)°] but a less regular W-shaped conformation for the other [torsion angle = 147.4 (2)°].
