Abstract
A summary of the resource.
This study reports a new octadentate tricarboxylate appended ligand (H4dphta) with enhanced relaxivity and high stability towards Gd(III) complex as an MRI probe. The designed ligand was synthesized in multiple steps. Both, the ligand and its complex were characterized by spectroscopic techniques. Structural analysis of Gd(III) complex by single crystal XRD confirms its mono-hydrated form adopting distorted capped square antiprism geometry. Protonation constants of the ligand and the thermodynamic stability constant of the [Gd(Hdphta)] and [Gd(H2dphta)]+ species have been found as log K110 = 18.6(1) and log K111 = 24.8(1) at 25.0 ◦C, and I = 0.15 mol⋅L

Abstract
A summary of the resource.
In the present work, we investigated the proton-transfer reactions of Re(II)-nitrosyl complexes bearing halides and nicotinic acid (Hnic) or 6,6́-dinicotinic acid (H2dinic) trans-coordinated to the core {ReNO}3+ by potentiometry and UV - Vis absorption spectroscopy in a mixture DMSO:H2O (1:1; v:v). The presence of Hnic and H2dinic in title complexes promotes a marked decrease in the acidity (higher pK values) compared to the noncoordinated pyridine-derived ligands. The UV - Vis measurements indicate that the absorption spectra of complexes do not show any dependence on the acidity of the medium and the number of non-coordinated carboxylic units. Time-dependent Density Functional Theory (TD-DFT) calculations are performed to understand the optical properties of complexes and their response upon deprotonation. TD-DFT studies are conducted with PBE1PBE in combination with LANL2TZ on rhenium and 6–311++G(d,p) on non-metal atoms within the CPCM approach. This methodology shows a reasonable match between the measured and simulated spectra keeping the computational cost low. The nature of all absorption bands is ascribed to a ligand-metal-to-ligandmetal charge transfer (LMLMCT), in which negligible contribution from carboxylic units is detected.

Abstract
A summary of the resource.
Polynuclear complexes are widely regarded as potential materials in separation, catalysis, gas storage, and molecular recognition. Those complexes including lanthanide (Ln) ions in the heterobimetallic assembly enhance the structural flexibility and increase the thermodynamic stability. Up to now, the studies on these heteropolynuclear complexes have been mostly focused on lanthanide-copper compounds in the solid state. We have expanded the studies to solution chemistry, to know if such polynuclear species can also exist in aqueous solution. In this work, potentiometric titrations (25.0 °C, and I = 0.50 M Me4NCl) were carried out for systems containing a Ln ion (La, Ce, Sm), a bridging ligand (oda or ida), and a second metal ion. We found that polynuclear units can be formed with MII (Mn, Fe, Co, Ni, Cu, Zn, Cd, and VO2+) and MIII (Fe, Al) ions, and can be predominant in aqueous solution. Species like [Ln2M3L6] or [Ln2M3L6(OH)n]n- (n = 3, 6) can exist in solution, representing the same 2:3:6 stoichiometry found in the solid state. The presence of an amino group in the ida ligand makes the mononuclear complexes with 3d metal ions more stable, preventing to some extent the formation of polynuclear complexes.
