The structure of the title compound (TM-BODIPY), C13H 15BF2N2, which can be used to synthesize molecular probes for labelling DNA and proteins, has been determined using a very small single crystal employing Cu K radiation and a two-dimensional multi-wire proportional detector. The molecules stack perpendicular to (904), forming a corrugated sheet-like structure when viewed along (3,0,10). 2006 International Union of Crystallography. All rights reserved.
