Manganese-indium compounds

Silicon electrodes can also be stabilized by depositing a layer of compounds of oxides and silicides such as Ru02, molybdenum dinitrogen complexes, manganese oxide, indium-tin oxide, " aluminum oxide and aluminosilicate. In contrast to the noble metals, deposition of islands of Pb and Cd tends to inhibit hydrogen evolution in H2SO4 solution. ... 

Allylation and propargylation of carbonyl compounds have been surveyed [5]. This section focuses on regio- and stereochemical aspects of the carbonyl allylation reactions in organic and aqueous media. Allylation of carbonyl compounds also proceeds under solvent-free conditions [10] or in liquid carbon dioxide [11]. Allylation with a catalytic amount of indium (0.01-0.1 equiv.) in combination with manganese and chlorotrimethylsilane has been reported [12]. Allylindium reagents have successfully been applied to syntheses of several natural products [13]. 

Various metal-metal single o-bonded complexes have been obtained by the reaction of metal carbonyls with metal-carbon o-bonded porphyrins or by the reaction of metal carbonyl anions and chlorometalloporphyrins (Scheme 14). For example, the reaction of dimanganese carbonyl and methyl indium(III) porphyrin gives manganese pen-tacarbonyl indium porphyrin In(Por)Mn(CO)5. The same compound is isolated when chloroindium porphyrin is allowed to react with the manganese pentacarbonyl monoanion. Various iron, cobalt, tungsten, and molybdenum complexes have been prepared by these two methods. 

The gallium and indium atoms maintain their typical tricoordination and do not interact with carbon monoxide which interacts only with the transition metal atoms (manganese). Such a behaviour means that non-transition and transition metal atoms maintain their own properties even when directly bound also in a complex cluster cage. In agreement with this point in a compound as Sn[Co(CO)4] 2 [Mn(CO)s] 2 [137] the cobalt and manganese atoms maintain their typical coordination as the tin atom. 

Cluster compounds containing members of the manganese triad are represented by a study detailing their reactions with gallium, indium and thallium . 

Although the structural chemistry of molybdenum and vanadium phosphates is very diverse these compounds seem to be prototypes for open framework transition and main group metal phosphates. Recent results have shown that zeolite-like compounds like zinc/cobalt phosphates [731, indium phosphates [74], nickel/aluminum phosphates [75], cobalt/boron phosphates [76], manganese and cobalt phosphonates with giant 44-membered rings forming ellipsoidal cavities [77] can be synthesized. All these examples show that the diverse chemistry of octahedral-tetrahedral framework structures is a vast field where...
