Application In Synthesis of Potassiumtris(1-pyrazolyl)borohydride. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about [Hydridotris(pyrazol-1-yl)borato-κ3N,N’,N”][5,10,15,20-tetrakis(4-methylphenyl)porphyrinato-κ4N,N’,N”,N”’]samarium(III) toluene 1.75-solvate. Author is He, Hongshan; He, Guishan; Ng, Seik Weng.
In the title complex, [Sm(C9H10BN6)(C48H36N4)]·1.75C7H8, there are two independent complex mols. in the asym. unit, in each of which the SmIII ion is coordinated by seven N atoms, four from a (4-methylphenyl)porphyrinate ligand and three from a hydridotris(pyrazol-1-yl)borate ligand, to form a capped trigonal-prismatic geometry. The SmIII ion is ‘sandwiched’ between two ligands and is located 1.2647(13) and 1.2549(14)Å from the porphyrin ring in the two complex mols. The asym. unit also contains 3.5 mols. of toluene, the half-occupancy mol. being located close to a crystallog. inversion center. The porphyrin groups have ‘dome’-like geometries.
