Synthesis, structure and luminescent properties of zinc(II) and Hg(II) complexes with substituted 1,10-phenanthroline

Abstract

Two d 10 group 12 metal complexes, 2-(2-methoxyphenyl)-1,10-phenanthroline zinc dichloride (2a) and 2-(2-methoxyphenyl)-1,10-phenanthroline mercury dichloride (2b) were synthesized and characterized by IR, 1 H and 13 C NMR as well as elemental analysis. Structure of 2b in the solid state was determined by single-crystal X-ray crystallography, revealing that 2b is four-coordinate in a distorted tetrahedral geometry with the methoxy group uncoordinated. Luminescent properties of 2a and 2b in solution and the solid state were studied.

Anion channel structure through packing of cucurbit[5]uril-Pb2+ or cucurbit[5]uril-Hg2+ complexes

“…A number of structures of Pb 2þ and Hg 2þ complexes have been published in the past few years [36][37][38][39][40][41][42][43][44]. For example, Marandi et al [36][37][38] reported a series of Pb 2þ Symmetry transformations used to generate equivalent atoms: #6: Àx, Ày þ 1, Àz; #7: Àx À 1/2, y þ 1/2, Àz þ 1/2; #8: x, y þ 1, z; #9: Àx À 1/2, y À 1/2, Àz þ 1/2.…”

“…Gao et al [39] synthesized Hg 2þ complexes with substituted 1,10-phenanthroline and studied its luminescent properties. Similar to these ligands, cucurbit [5]uril can coordinate to Pb 2þ and Hg 2þ .…”
