“…Two cases have been reported in the literature, where such chemical reactivity is observed. The first one was in the case of Cd(II), where the metal ion interacted with maleic acid and the finally arising lattice contained the compound with the molecular formula [Cd(fum)(phen)] . The second example was in the case of V(IV), where the starting ligand was malic acid and the final lattice contained the compound with the molecular formula {[V(phen) 3 ](fum)}(OH) 2 ·10H 2 O .…”

Variable-pH hydrothermal reactions of Pb(II) with dicarboxylic acids in the presence of 1,10-phenanthroline led to new solid-state compounds [Pb 2 (C 12 4). All compounds were characterized by elemental analysis, FT-IR, CP-MAS NMR, and single crystal X-ray diffraction. The collective chemical reactivity in the ternary Pb(II)phenanthroline-dicarboxylate systems unravels seldom seen metal-assisted ligand malate/maleate to fumarate transformations, which in the presence of Pb(II) and 1,10-phenanthroline contribute to the assembly of 2D (2) and 3D lattice networks (3 and 4). All distinct assemblies in 1-4 reveal interwoven crystal lattice connections, reflecting unique physicochemical properties.

“…38 Several in-situ ligand syntheses have been observed in hydrothermal systems. [39][40][41][42][43][44][45][46][47] Under these conditions, the insitu formation of organic linkers often relies on the rearrangement or cleavage of organic compounds. The rearranged organic species are then observed in the crystalline reaction products.…”

“…This approach offers the advantages of simplified synthesis, slow ligand formation to promote single-crystal growth, environmental friendliness, and in some cases a novel pathway to new materials − Under these conditions, the in-situ formation of organic linkers often relies on the rearrangement or cleavage of organic compounds. The rearranged organic species are then observed in the crystalline reaction products.…”

A novel templated uranium oxalate/glycolate, (UO2)4(O)2(C2O4)(H2C2O3)2.2[(C8H20)N] (a = 7.9230(8) A, b = 13.3793(13) A, c = 17.4141(18) A, beta = 96.006(2) degrees , monoclinic, P21/n, Z = 2), has been synthesized under hydrothermal conditions via in-situ ligand synthesis. The oxalate and glycolate anions have been formed through the oxidation of 1,4-diazabicyclo[2.2.2]octane, which proceeds through intermediates such as piperazine and ethylene glycol. Reported herein is the synthesis of this compound, crystal structure, and mechanistic information regarding the oxidation pathway.

“…Hence in situ reactions have greener chemistry than traditional syntheses. Until now, several types of in situ reactions like hydrolysis, hydroxylation, ether bond formation, carbon–carbon bond formation, cycloaddition, decarboxylation, isomerisation, amination and nitration of aromatic rings have been reported in the presence of various metal ions. Thus, the metal ions are generally believed to act as catalysts in the process of in situ ligand formation…”

A new dinuclear Al(III) complex has been prepared by in situ Friedel-Crafts sulfoxidation of 2-naphthol with thionyl chloride (SOCl 2 ) and AlCl 3 as catalyst. The product was characterized by elemental analysis, spectroscopic methods and single crystal Xray analysis. X-ray diffraction indicated that the product is a centrosymmetric dinuclear Al(III) complex, [Al(bn)(μ À OCH 3 ) (CH 3 OH)] 2 (1), where bn 2À is a O 3 -donor 1,1'-sulfonylbis(naphtholate) ligand obtained by in situ reaction of materials. The coordination environment around the Al(III) ions is distorted octahedral (AlO 6 ) and the Al(III) ions are connected together by methoxy bridging ligands. Complex 1 crystallizes in triclinic system and Al(III)⋅⋅⋅Al(III) separation is 2.886(2) Å. The dimeric structure is stabilized by two intramolecular O À H⋅⋅⋅O hydrogen bonds, while the intermolecular interactions are provided by C-H⋅⋅⋅π and π-π contacts.
