A heterometallic metal-organic framework,Ag In(nicotinate)4·1.5DMF,was obtained from the reaction of nicotinic acid,Ag NO3 and In(NO3)3 in DMF.The complex was characterized by elemental analysis,infrared spectrum,thermogravimetric analysis,powder X-ray diffraction and single-crystal X-ray diffraction.Crystal data are:C28.5H26.5N5.5O9.5Ag In,orthorhombic space group I222,a=10.775(15),b=11.939(18),c=13.93(2) ?,V=1792(5) ?3,Z=2,Dc=1.521 mg/m3,μ=1.244 mm-1,F(000)=816,the final R=0.0672 and w R=0.1812 for 1912 observed reflections with I > 2σ(I).Single-crystal X-ray structure analysis reveals that nicotinate bridges In(III) and Ag(I) through carboxylate chelating with In(III) and pyridyl nitrogen atom coordinating to Ag(I),generating a new 2D network consisting of tetrahedral building units of [Ag N4]+ and [In(COO)4]-.
