چکیده
The title manganese(II) substituted gallophosphate, K(0.5)Rb(0.5)[Ga(2)Mn(PO(4))(3)(H(2)O)(2)], features a three-dimensional network built of PO(4) tetra-hedra, GaO(5) trigonal bipyramids and MnO(6) octa-hedra. The Rb(I) and K(I) ions, which are disordered with respect to each other in a 1:1 ratio, occupy sites within the channels of the framework. The Rb(I)/K(I) and Mn(II) atoms occupy positions of 2 symmetry, as does one of the two P atoms. The Rb(I)/K(I) site is surrounded by six O atoms [2.996 (2)-3.178 (4) Å] in an irregularly-shaped coordination environment. O-H⋯O hydrogen bonds between the water molecules and phosphate O atoms consolidate the crystal packing.

The title compound, potassium nickel(II) digallium tris-(phosphate) dihydrate, K[NiGa(2)(PO(4))(3)(H(2)O)(2)], was synthesized hydro-thermally. The structure is constructed from distorted trans-NiO(4)(H(2)O)(2) octa-hedra linked through vertices and edges to GaO(5) trigonal bipyramids and PO(4) tetra-hedra, forming a three-dimensional framework of formula [NiGa(2)(PO(4))(3)(H(2)O)(2)](-). The K...
متن کاملPhotoinduced oxidation of a water-soluble manganese(III) porphyrin.
The photoinduced oxidation of tetra(N-methyl-4-pyridyl)porphyrinmanganese(III) has been achieved in homogeneous solution. The manganese porphyrin was used as an electron donor in a three-component system with tris-(2,2'-bipyridine)ruthenium(II) as the photosensitizer and chloropentaamminecobalt(III) as the electron acceptor. The photooxidized manganese porphyrin is unstable in aqueous solution,...

The title compound, [Mn(2)(C(18)H(18)N(2)O(2))(2)(C(7)H(5)O(2))(2)]·2H(2)O, was synthesized by the reaction between manganese(II) benzoate and the Schiff base generated in situ by the condensation of ethane-1,2-diamine and o-hydroxy-aceto-phen-one. The Jahn-Teller-distorted manganese(III) ions of the centrosymmetric dimer are connected through phen-oxy bridges. Hydrogen-bonding inter-actions be...
متن کاملMicrowave synthesis of Tris-(1,10-phenanthroline)Manganese(II) complex and its electrochemical sensing property of catechol
Tris-1,10-phenanthroline manganese(II) complex was synthesized by microwave irradiation. The synthesized complex was characterized by UV-visible and FT-IR spectroscopy. Its electrochemical behaviour was examined by cyclic voltammetry (CV). The tris-1,10-phenanthroline manganese(II) complex was used for the electrochemical sensing of catechol. The manganese ion gets reduced as the oxidation of c...
متن کاملReaction of [60]fullerene with free radicals generated from active methylene compounds by manganese(III) acetate dihydrate.
The reaction of [60]fullerene with dimethyl malonate and diethyl malonate in the presence of manganese(III) acetate dihydrate (Mn(OAc)3.2H2O) for 20 min afforded singly bonded [60]fullerene dimers 1a and 1b in a 1,4-addition pattern. When the reaction time was extended to 1 h, 1,4-bisadducts 2a and 2b were obtained. Unsymmetrical 1,4-adduct 5 and C2 symmetrical 1,16-bisadduct 6 were obtained wh...
