New main-group metal dipyrrinato complexes [M(4-pyrdpm)(3)], where M = Ga3+ or In3+ and 4-pyrdpm is the anion of 5-(4-pyridyl)dipyrrin (4-pyrdpmH), have been synthesized and incorporated into metal-organic frameworks (MOFs) by reacting the dipyrrinato complexes with silver(I) salts. MOFs formed with AgOTf (OTf = O3SCF3) and AgSbF6 gave frameworks with three-dimensional (10,3) and two-dimensional (6,3) topologies, respectively. In contrast, AgPF6 produced both (10,3) and (6,3) network topologies, suggesting that the PF6 anion has little preference for templating (10,3) versus (6,3) frameworks within this system. These findings update an earlier MOF study that examined the role of these anions in templating related heterometallic MOFs which used [Fe(4-pyrdpm)(3)] and [Co(4-pyrdpm)(3)] metalloligands. All of the dipyrrin compounds reported here have been characterized by singlecrystal X-ray crystallography, including the first crystallographically characterized example of a 1,2,3-unsubstituted free-base dipyrrin, 4-pyrdpmH.
