Abstract
A novel MnⅡ complex [{Mn(IBG)(2,2'-bipy)(H2O)}·4H2O]n 1(H2IBG=isophtha-loylbisglycine and 2,2'-bipy = 2,2'-bipyridine) has been synthesized and characterized by singlecrystal X-ray diffraction,elemental analysis,IR spectra and thermogravimetric analysis.It crystallizes in monoclinic,space group P21/n,with a=13.667(2),b=14.045(2),c=14.195(2),β=101.483(3)°,V=2670.1(7)3,Z=4,C22H26N4O11Mn,Mr=577.41,Dc=1.436 g/cm3,F(000)=1196.0,μ(MoKα)=0.558 mm-1,the final R=0.0578 and wR=0.1460 for 2974 observed reflections with I2σ(I).In the structure,the MnⅡ atom is coordinated in a distorted octahedral environment arranged by one water molecule,one 2,2'-bipy ligand and two IBG ligands.
