{2-[(3,5-Dimethyl-2H-pyrrol-2-yl­idene-κN)(4-nitro­phen­yl)meth­yl]-3,5-dimethyl-1H-pyrrol-1-ido-κN}difluoridoboron

In an effort to discover novel and potential boron–dipyrromethene (BODIPY) dyes, the title compound, C(19)H(18)BF(2)N(3)O(2), was prepared from 2,4-dimethyl­pyrrole, 4-nitro­benzaldehyde and BF(3)·Et(2)O in a one-pot reaction. There are two independent mol­ecules, A and B, in the asymmetric unit in...

Sumario:In an effort to discover novel and potential boron–dipyrromethene (BODIPY) dyes, the title compound, C(19)H(18)BF(2)N(3)O(2), was prepared from 2,4-dimethyl­pyrrole, 4-nitro­benzaldehyde and BF(3)·Et(2)O in a one-pot reaction. There are two independent mol­ecules, A and B, in the asymmetric unit in which the dihedral angles between the benzene ring and boron–dipyrromethene mean plane have significantly different values [82.71 (8)° for mol­ecule A and 73.16 (8)° for mol­ecule B]. Inter­molecular C—H⋯π inter­actions help to stabilize the crystal structure.
