“…The lead(II)-oxygen vibrations appear at frequencies similar to those observed in other lead(II) complexes [44,45]. The bands at 411 cm -1 for 1, and 418 cm -1 for 2 can be assigned to the Pb-N stretching vibration [8].…”

“…A frequently discussed issue in the coordination chemistry of lead(II) ion is the stereochemical activity of valence shell lone electron pair [8,[50][51][52][53]. The arrangement of the donor atoms in 1 suggests the existence of a stereochemically active lone pair (SALP) on the open side of the coordination polyhedron (Fig.…”

“…The incorporation of Pb(II) metal ion in the coordination and coordination polymeric systems, in view of their interesting properties and structural features (e.g., adoption of different coordination numbers and the possible occurrence of stereochemical activity for their valence shell lone electron pairs) has been of great interest, in recent years [6][7][8][9][10][11][12].…”

“…We have recently reported the crystal structure of a novel tetranuclear coordination complex of lead(II) with 6-methyl-2,2 0 -bipyridine (mby) and nitrate ion ligands, [Pb 4 (NO 3 ) 8 (mbpy) 4 ] [23]. Among the possible coordination modes of nitrate ligand with Pb(II) (Scheme 1), this compound uniquely contains two tridentate chelating/bridging mode (ivb), four bi-chelating mode (iii) together with two bidentate bridging mode (ii).…”

Lead(II) coordination polymer [Pb(5,5 0 -dmbpy) (l-NO 3 ) 2 ] n (1) and mononuclear complex [Pb(6,6 0 -dmbpy) (NO 3 ) 2 ] (2) (where 5,5 0 -dmbpy is 5,5 0 -dimethyl-2,2 0 -bipyridine and 6,6 0 -dmbpy is 6,6 0 -dimethyl-2,2 0 -bipyridine) were synthesized from reaction of lead(II) nitrate with 5,5 0 -dmbpy and 6,6 0 -dmbpy, respectively. Both complexes were thoroughly characterized by elemental analysis, infrared, 1 H and 13 C NMR, UV-Vis, emission spectroscopy, as well as single-crystal X-ray diffraction. Polymer 1 possesses one-dimensional (1D) chain structure, whilst complex 2 exhibits a discrete complex which provide an extended chain parallel to the [001] direction, via weak intermolecular C-HÁÁÁO hydrogen bonding. Coordination number of Pb 2? in 1 and 2 are 8 and 6, respectively, with the stereochemically active lone pair, resulting in the hemidirected geometry for both complexes. The nitrate anions exhibit a tridentate chelating/bridging mode in 1, and a bi-chelating mode in 2. The supramolecular features in these complexes are guided/influenced by weak directional intermolecular C-HÁÁÁO hydrogen bonding (1 and 2) together with p-p and C-HÁÁÁp (1) interactions. The luminescence studies of 1 and 2 confirmed that the position of methyl substituent on 2,2 0 -bipyridine rings has a profound effect on the fluorescence emissions.

“…[38] For 3, the luminescent emissions can be attributed to a metal-centred transition involving the s and p metal orbitals, which has been commonly observed in other s 2 -metal complexes. [39,40] Compared with 2, the central metal ions of 3 may be joined together by nitrogen and terminal sulfur atoms of the ligands, which cannot produce a large conjugated system, resulting in the reduction of the luminescence intensity. Complex 6 displays very weak luminescence with almost no emission, which is attributed to the heavy-atom effect (the graph of 6 is omitted).…”

Six coordination complexes were solvothermally synthesised: a 3D framework [Cd(tmtt)2]n (1), 2D architectures [Zn(tmtt)2]n (2) and [Pb(tmtt)2]n (3), 1D chain structures [Ni(tmtt)2·(H2O)2]n (4) and [Co(tmtt)2·(H2O)2]n (5), and a mononuclear structure [Hg(tmtt)2] (6). The complexes, based on self-assembly of different metal ions with a newly designed mercapto-thiadiazole ligand tmttH (tmttH = 5-[(1H-1,2,4-triazol-1-yl)methyl]-1,3,4-thiadiazole-2(3H)-thione), were characterised by single crystal X-ray diffraction analyses. Crystal structure analyses reveal that complex 1 exhibits a four-fold interpenetrating 3D framework with {64.82} topology based on two kinds of right-handed single-helical chains, 2 displays a bilayer structure, 3 presents a crown-shaped network, 4 and 5 show 1D double–helical chain structures, and 6 is a mononuclear structure. Moreover, the thermal stabilities of crystalline samples 1–6 have been investigated, and the luminescent properties of complexes 1, 2, 3, 6, and the free ligand have been studied. The results of photoluminescent measurements illustrate that 2 and 3 may serve as excellent candidates for potential photoactive materials.
