In the crystal structure, the molecules are linked by a weak C—H(arene) interaction along [010] involving the phenyl CH group and the phenyl rings. There are no further significant intermolecularinteractions PB International Union of Crystallography SN 2056-9890 YR 2009 FD 2009 LK http://hdl.handle.net/10347/23315 UL http://hdl.handle.net/10347/23315 LA eng NO C.
