Benzene carboxylate-bridged

Two-dimensional networks have been formed by four square carboxylate-bridged di-metal(II) building units using the reaction of Zn(N03)2 or Cu(N03)2 with benzene-1,3-dicarboxylate in methanol or DMF in the presence of pyridine [125], Hydrothermal treatment of Ni(N03)2 with disodium fumarate in water at 170 °C leads to a complex [Ni2(fumarate)2-H20] with a three-dimensional polymeric structure formed by chains of fused Ni(II) octahedral units [126]. Nickel succinate presents a remarkable three-dimensional Ni-O-Ni framework with porosity and high thermal stability (-400 °C) [127]. A two-dimensional... 

In polar solvents such as alcohols, the carboxylate bridges are broken, and the following monomeric complexes are formed [Rh(RCOO)(CO)2 (ROH)]. In methanol-benzene solutions, an equilibrium exists between dimers Rh2(RCOO)2 (CO)4 and monomers Rh(RCOO)(CO)2 (MeOH), where R = H or...

The only substrate of that type with a longer bridge between the carboxylic acid and the allene is 122, which was isomerized in an exo-dig manner to the six-mem-bered lactone 123 on the surface of yellow HgO in benzene (Scheme 15.37) [84]. 

While palladium carboxylates generally decompose in a CO atmoshere to give metal, the compounds [Pd(02CR)(C0)]-nRC02H (n = 0, 0.5 R = Me, CDs, Et or Ph) have been prepared from the corresponding Pd acetate in carboxylic acid-benzene solution. A crystallographic study on the acetate complex showed it to have the tetrameric structure (20). The compound consists of two dimeric palladium(I) units linked by acetate bridges.
