Abstract
The structures of the 1∶2 molecular complexes oftrans-9,10-dihydroxy-9,10-diphenyl-9,10-dihydroanthracene with 4-methylcyclohexanone (1) and with 2-methylcyclohexanone (2) have been determined by X-ray crystallography. The crystal data are as follows: Compound (1):P22/c,a=8.838(2) Å,b=8.92(1) Å,c=20.879(8)=Å,β=98.67(2)°,V=1627(2) Å3,Z=2 andR=0.062 for 2201 unique MoKα reflections; Compound (2):P¯1,a=8.917(3) Å,b=9.900(2) Å,c=11.250(4) Å,a=68.72(2)°,β=64.39(3)°, γ=74.86(2)°,V=828.1(5) Å3,Z=1 andR=0.098 for 2563 unique reflections. Both inclusion compounds exhibit O-H⋯O=C hydrogen bonding interactions. The thermal properties of these compounds have been characterized by DTA and TGA thermograms.
