1.10- Phenanthroline monohydrate

Determination of Azide as NaNt. Pipette a 25 ml portion of the sample into a 500 ml Erin flask and dil with w to 150-200 ml. Titrate with 40% sulfuric acid to just fo the phpht end-point, not overrunning it. Add N/10 ceric sulfate soln in 5 ml portions until the soln becomes deep yel, indicating an excess of ceric sulfate. Record the exact amt used. Add 10 ml of 40% sulfuric acid and 2 drops of o-phenanthroline indicator (prepd by dissolving 14.85 g of o-phenanthroline monohydrate, CiaHsNa HaO in 1 1 of 0.025 M freshly prepd ferrous sulfate... 

X-ray diffraction studies on hydrated triorganotin compounds H2O — SnRsX have provided several examples of water engaged in inner-sphere coordination to tin in five-coordinate molecules. For inner-sphere coordination, the complexes tend to pack in arrangements in which the number of hydrogen bonding interactions involving the coordinated water molecule is maximized. For example, o-phenanthroline monohydrate, which chelates to a plethora of transition metals, forms with triphenyltin chloride an outer-sphere coordination complex in which the coordinated water molecule [O — Sn = 2.42 A]... 

To the product from Step 1, 1,10-phenanthroline monohydrate (2.97 mmol) dissolved in 1.5 L THE containing N,N-tetramethylenediamine (893 mmol) was added ethyl magnesium bromide (348.1 mmol) in THE along with trimethylchlorosilane (325.9 mmol) until a phenanthroline color change occured. The mixture was cooled to — 27 °C until the halide... 

An 0.025 M solution of orZ//o-phenanthroline-ferrous ammonium sulfate indicator is prepared by dissolving 1.487 g of orzAo-phenanthroline monohydrate in 100 ml of an aqueous ferrous ammonium sulfate solution, containing 0.980 g of ferrous ammonium sulfate hexahydrate per 100 ml. 

Ferroin indicator Dissolve 1.485 g 1,10 phenanthroline monohydrate in about 80 ml water (warm if necessary and then cool) and added 0.69 g ferrous sulphate heptahydrate. Stir to dissolve and dilute to 100 ml. 

A sample of 1,10-phenanthroline monohydrate (3.96 g, 20 mmole) in 20 mL ethanol is added to a solution of copper(II) chloride dihydrate (3.40 g, 20 mmole) in 40 mL ethanol. A suspension of a green-blue solid develops immediately. A solution of malonic acid (2.08 g, 20 mmole) in 50 mL ethanol is then slowly introduced into this suspension, which is being stirred magnetically. This...
