Oxalate ion has a strong antioxidative ability and can effectively inhibit the oxidation of SnIIduring the synthesis. Besides, oxalate as a bidentate capping ligand is shown to be coordinated on the surface of formed NCs. This can not only passivate the uncoordinated Sn on the surface but also ...
In this, each oxalate ion acts as a bidentate ligand for the uranyl ion and tetradentate in bridging two groups. In bisoxalato-dioxouranate (VI) complexes, however, two water molecules are assumed to complete the hexagonal arrangement. However, substitution reaction on the bisoxalato complex ...
Each copper(II) ion in 1 is four-coordinate in a square planar environment defined by two amidate-nitrogen and two carboxylate-oxygen atoms from the two oxamate groups of the obpa ligand. The manganese(II) ion is six-coordinate in a somewhat distorted octahedral surrounding that is built by...
Structure, Isomerism, and Ligand Dynamics in Dioxouranium(VI) Complexes The ligand exchange reactions in complexes of the type UO2LFn(H2O)3-n, where n = 13 and L is one of the bidentate ligands picolinate (pic), oxalate (ox), c... Z Szabó,W Aas,I Grenthe - 《Inorganic Chemistry》...
The difference between νas(COO) and νsym(COO) stretching frequencies is 255 cm−1 indicating a bidentate or a terminal monodentate coordination mode of the oxalate ligand in the complexes [24]. The bands at 822 cm−1 is attributed to the bending vibration of O–C–O and the ...
Because oxalate is not present in the starting reaction mixture, it may be derived from the reduction of squarate ligand. In 1, Cu(II) ions exhibit two different coordination environments, forming a distorted octahedral geometry. The Cu1 is coordinated with six oxygen atoms from two bidentate ...
Oxalate ion has a strong antioxidative ability and can effectively inhibit the oxidation of Sn-II during the synthesis. Besides, oxalate as a bidentate capping ligand is shown to be coordinated on the surface of formed NCs. This can not only passivate the uncoordinated Sn on the surface but ...
The analysis of the crystal structure revealed that the oxalate ligand is in bis(bidentate) coordination mode between two copper(II) centres. The other four positions of the coordination environment of the copper(II) ion are occupied by one water molecule, a bidentate bipy ...
