Hydrothermal Synthesis, Crystal Structure and Spectroscopic Investigations of [Y(C6NO2H5)3(H2O)2]n(1.5nZnCl4)•nH2O with Unprecedented Polycationic Chains
A new heterometallic 4f-3d complex [Y(C6NO2H5)3(H2O)2]n(1.5nZnCl4). nH2O(1), was synthesized via a hydrothermal reaction and structurally characterized. Complex 1 crystallized in the monoclinic system with space group P21/c: a=0.94847(9) nm, b=2.0947(2) nm, c=1.6001(2) nm, β=104.467(2)°, V-3.0781(5) nm3, Mr=823.04, Dc=1.776 g/cm3, S=1.009, μ(Mo Kα)=3.603 mm−1, F(000)=1632, R=0.0787, and wR=0.2273. Complex 1, with four formula units in a cell, was characteristic of a one-dimensional polycationic chain-like structure. Photolumincscent investigation showed that the title complex displayed a strong emission in the blue region, which was attributed to the intraligand π-π* transition of the nicotinic ligands. Optical absorption spectrum of complex 1 revealed the presence of a wide optical bandgap of 4.17 eV.
