Abstract

A heterometallic 4f-5d inorganic-organic metal-isonicotinato hybrid Gd(C6NO2H5)3-(H2O)22n·(nH5O2)(nHgCl5)(2nHgCl4)·(2nH2O) 1 has been synthesized via hydrothermal reaction and structurally characterized.Complex 1 crystallizes in the space group C2/c of monoclinic system with four formula units in a cell:a=24.234(8),b=20.816(7),c=15.333(3),β=128.091(8)°,V=6088(3)3,C36H47Cl13Gd2Hg3N6O20,Mr=2260.92,Dc=2.467 g/cm3,S=0.896,μ(MoKα)=10.331 mm-1,F(000)=4216,R=0.0344 and wR=0.0629.The crystal structure analysis reveals that the title complex is characteristic of a one-dimensional chain-like structure.Photoluminescent investigation reveals that the title complex displays a broad and intense emission in the green region.
