Abstract
The crystal structure of bis[mu-3-(2-pyridyl)-1H-pyrazolato]-1 kappa(2 )N', N-2: 2 kappa N'; 1 kappa N': 2 kappa N', loro(dimethylformamide-O )indium]-dimethylformamide (1/2), [In2Cl4L2(dmf)(2)].2dmf [where HL is 3-(2-pyridyl)-pyrazole, C8H7N3, and dmf is dimethylformamide, C3H7NO] , contains pairs of [InCl2(dmf)] fragments linked by two pyrazolate br idges from the deprotonated bridging ligand 3-(2-pyridyl)pyrazolate (L -). This ligand acts as a bidentate N-donor chelate to one metal centr e using the pyridyl N and pyrazolyl N-2 atoms, and bridges to the othe r metal using the (deprotonated) pyrazolyl N-1 atom. Each In-III centr e, therefore, has an N3Cl2O donor set.
