Badger and W. Sasse, J. Figgis and J. Lewis and R. Wilkins Ed. Thermobalance experiments made use of an automatic reAnal. Found: Zu, 7. The compound is much less solub'e than the bipyridine X,K'-dioxide in the molar ratio of and the resultanalogous compounds. I t could be dissolved in D M F for coning solution then is allowed to cool slowly to room temperature.
Found: Cd, Unless otherwise H , 3.
Preparation of the Tetrachloroplatinate Complexes, [Mstated the compounds are very soluble in boiling water 5 ml. After cooling to room temperature, the almost clear solution was acetone, chloroform, benzene, and tetrahydrofuran. The color, filtered and treated slowly with stirring with the required stoidecomposition temperature, and analytical figures for the chiometric amount of a filtered solution of K2PtC14 in water.
A precipitate separated, which was filtered off, washed three Tris- 2,2'-bipyridine N,N'-dioxide -chromium II1 Perchlotimes with small amounts of cold water and twice with ra. T o obtain this compound in a The compounds are readily soluble in boiling water, moderately pure state the reaction mixture was refluxed for 1 hr. The color, decomposition temperature, and C, Found: Cr, 5. The compound decomposes very rapidly to a black was carried out in a darkened room. The yields and purity of the powder in the presence of light and less rapidly in the dark.

The product was dried over phosphoric product from boiling water in the dark. Owing t o the great anhydride in vatu0 for 12 hr. Found: M n , 6. In the crystalline state, the complex is quite stable to light for Tris- 2,2'-bipyridine N,N'-dioxide -iron II1 Perchlorate about 1 hr. Found: Fe, 5. Found: Co, 6. I n a thermobalance experiment, 0. I t exists as small yellow-green needles C, Found: Ni, 6. C1, Found: Cu, 7.
Bear and u'. Wendlandt, J. Wendlandt and J L. Bear, ibid. Bear, J. Bis- 2,2'-bipyridine N,N'-dioxide -copper 11 TetrachloroAnal. Deep olive-green crystals were formed, which on powdered solid with water for 4 hr. These complex salts generally on a water bath. The solid residue then was stirred with ml. For instance, thermocrop of violet crystals. These were filtered off, thoroughly washed with ethanol, and dissolved in ml. The solution was filtered and 2H20 still retains one molecule of water a t '.
Background & Summary
This treated slowly, with stirring, with a solution of NaC 2 g. A precipitate formed, which was collected, a t which temperature the compound decomposes. Clod , are remarkably stable to air and light, with Anal. In aqueous solution they are N, 8.
Basic chemical concepts
The crystalwith decomposition in hot water, soluble in D M F when warmed line salts have a high thermal stability. On repeated preparation, the compound always was obtained as the are unaltered up to ' but a t higher temperatures above described very fine purple crystals. No evidence is availexplode; for example, the above-mentioned Co I1 able t o decide which of the two possible cis-trans isomers of complex explodes violently a t about '.
