Chemistry of lanthanide–metal carbonyl systems: the ytterbium–chromium carbonyls interaction

Assembling Process of Charged Nonanuclear Cationic Lanthanide(III) Clusters Assisted by Dichromium Decacarbonyl Hydride

“…FTIR spectra in Nujol mull of 1a − e show three sharp bands in the ν(CO) region at 2030 (m), 1940 (vs), 1868 (s) cm -1 characteristic of the square pyramidal ( C 4 v ) arrangement of the M(CO) 5 carbonyl groups. . In the 3800−3200 cm -1 region, a hydroxo sharp band at 3576 cm -1 that has been attributed to the stretching mode of μ 3 OH is accompanied by a broad peak, in the apparent range of the OH stretching bands of water (3350 cm -1 ), whereas the coordinated β-diketonate ligand exhibits splittings and shifts as well as intensity changes in the 1650−400 cm -1 region.…”

Electronic Structures and Properties of Bimetallic Plutonium Group 13 Carbonyl Compounds [XPuCO] (X = B, Al, and Ga)

“…As known, the formation of carbonyl complexes via a metal reacting with carbon monoxide (CO) has been reported for almost all elements in the periodic table, − including s-, p-, d-, and f-block metal elements. The chemistry of metal carbonyl complexes has attracted considerable theoretical and experimental interest because the bonding interactions between metals and CO act as suitable models for fundamentally understanding their chemical bonding , and the formation of stable metal–metal bond complexes . Various monometallic and bimetallic main-group elements and transition-metal carbonyl complexes have been characterized by both experimental and quantum chemical studies .…”

“…The chemistry of metal carbonyl complexes has attracted considerable theoretical and experimental interest 13 because the bonding interactions between metals and CO act as suitable models for fundamentally understanding their chemical bonding 14,15 and the formation of stable metal−metal bond complexes. 16 Various monometallic and bimetallic main-group elements and transition-metal carbonyl complexes have been characterized by both experimental and quantum chemical studies. 17 Take group 13-bonded carbonyl complexes as an example: monometallic B(CO) n , 18,19 Al(CO) n , 20 Ga(CO) n , 21 and In-(CO) n (n = 1 and 2) and bimetallic B 2 (CO) 2 , 18,22 B 2 (CO), 23 Al 2 (CO), Al 2 (CO) 2 , 24,25 Ga 2 CO, and In 2 (CO) 21 have been produced in the gas phase under certain conditions.…”

Synthesis and X-ray crystal structure of cationic polynuclear hydroxide acetylacetonate lanthanide(III) clusters with homodinuclear or heterodinuclear decacarbonyl hydrides: [HMo2(CO)10]− and [HCrW(CO)10]−

“…A variety of lanthanide clusters have been obtained as tetra [14,15], penta [16], hexa [15b,e,17] octa [18], nona [19] [21], the synthesis was made by hydrothermal reaction with the aid of 1,4-naphtalene dicarboxylate (1,4-NDA) that give rise to porous lanthanide polymers having a dicubane like structure of the hydroxo core that is a frequent structural motif in lanthanide hydroxo clusters. As part of our program of developing new polynuclear lanthanide oxo-cluster compounds containing transition metals [22][23][24] we report the synthesis and spectroscopic characterization of Sm 9 (acac) 16 (OH) 10 [CrW(CO) 10 (-H)] and of the compounds having general formula Ln 9 (acac) 16 (OH) 10 …”
