(Mesitylene)molybdenum tricarbonyl arises from the reaction of molybdenum hexacarbonyl with hot mesitylene: [1]. Mo(CO) 6 + (CH 3) 3 C 6 H 3 → Mo(CO) 3 [(CH 3) 3 C 6 H 3] + 3 CO It can also be synthesized, with good yields by displacement of pyridine ligands of the trispyridine complex Mo(CO) 3 (pyridine) 3 in the presence of Lewis acids.
Callaway County is a county located in the U.S. state of Missouri.As of the 2020 United States Census, the county's population was 44,283. [1] Its county seat is Fulton. [2] With a border formed by the Missouri River, the county was organized November 25, 1820, and named for Captain James Callaway, grandson of Daniel Boone. [3]

Blair Jr. Republican: June 8, 1860 – June 25, 1860 Seated by the House upon winning contested election. Resigned. Vacant: June 25, 1860 – October 3, 1860 John R. Barret : Democratic: October 3, 1860 –
The compound is prepared by thermal reaction of the triene with molybdenum hexacarbonyl: [2] C 7 H 8 + Mo(CO) 6 → (C 7 H 8)Mo(CO) 3 + 3 CO. The compound is a piano stool complex, consisting of Mo(CO) 3 bound to six carbon centers of the triene. The methylene group projects from the plane of the six coordinated carbon atoms.
Molybdenum hexacarbonyl is a popular reagent in academic research. [6]One or more CO ligands can be displaced by other ligands. [7] Mo(CO) 6, [Mo(CO) 3 (MeCN) 3], and related derivatives are employed as catalysts in organic synthesis for example, alkyne metathesis and the Pauson–Khand reaction.
The average household size was 2.42 and the average family size was 2.88. In the county, the population was spread out, with 23.80% under the age of 18, 6.20% from 18 to 24, 23.10% from 25 to 44, 27.30% from 45 to 64, and 19.60% who were 65 years of age or older.
U.S. Route 56 (US 56) is an east–west United States highway that runs for approximately 640 miles (1,030 km) in the Midwestern United States.US 56's western terminus is at Interstate 25 Business (I-25 Bus.), US 412 and New Mexico State Road 21 (NM 21) in Springer, New Mexico and the highway's eastern terminus is at US 71 in Kansas City, Missouri.
The dark-blue phosphorus-containing heteropolymolybdate P[Mo 12 O 40] 3− is used for the spectroscopic detection of phosphorus. [31] The broad range of oxidation states of molybdenum is reflected in various molybdenum chlorides: [26] Molybdenum(II) chloride MoCl 2, which exists as the hexamer Mo 6 Cl 12 and the related dianion [Mo 6 Cl 14] 2-.
