Efforts to comprehend the structural鈥搒pectrochemical correlations of crystalline metal鈥搊rganic framework materials of Pb(II) with (a)cyclic and aromatic chelators linked to photoluminescent applications led to the hydrothermal pH-specific synthesis of crystalline materials [Pb{H2BTC}(phen)(H2O)]n路2nH2O(1), [Pb2{CBTC}]n(2), [Pb4(phen)8{CBTC}2(H2O)4]3路70.3H2O(3), and [Pb{HCTA}(H2O)2]n路nH2O(4). X-ray studies showed that 1鈥?b>4 exhibit unique architectures linked to 2D鈥?D coordination polymers formulated by Z-type units composed of Pb2O2 cores, unusually high number of lattice鈥搘ater molecules, and 蟺鈥撓€ and H-bond interactions. The contribution of the nature鈥搒tructure properties of the aliphatic-(a)cyclic organic (poly)carboxylic/aromatic chelators-ligands to binary-ternary Pb(II) reactivity weaves into the assembly of supramolecular networks, thereby providing clear structural鈥搒pectroscopic inter-relationships exemplifying the observed photoluminescent activity in a distinct MOF-linked fashion.
