Structural–Spectrochemical Correlations of Variable Dimensionality Crystalline Metal–Organic Framework Materials in Hydrothermal Reactivity Patterns of Binary–Ternary Systems of Pb(II) with (a)Cyclic (Poly)carboxylate and Aromatic Chelator Ligands
Efforts
to comprehend the structural–spectrochemical correlations of
crystalline metal–organic framework materials of PbÂ(II) with
(a)Âcyclic and aromatic chelators linked to photoluminescent applications
led to the hydrothermal pH-specific synthesis of crystalline materials

to 2D–3D coordination polymers formulated by Z-type units composed
of Pb<sub>2</sub>O<sub>2</sub> cores, unusually high number of lattice–water
molecules, and π–π and H-bond interactions. The
contribution of the nature–structure properties of the aliphatic-(a)Âcyclic
organic (poly)Âcarboxylic/aromatic chelators-ligands to binary-ternary
PbÂ(II) reactivity weaves into the assembly of supramolecular networks,

exemplifying the observed photoluminescent activity in a distinct
