Tetren

The kinetics of the reaction is first order in both nitrile complex and azide.909 NaN3 reacts with [Co(tetren)(NCMe)]3+ at pH 5.7 to give the 5-methyltetrazolato complex [Co(tetren)(N4CMe)]2+. The reaction is biphasic, involving the initial rapid formation of the AM-bonded tetrazole followed by the slow linkage isomerization to the N2-bonded complex.907... [Pg.78]

A. trans-BIS(TETRENNICKEL(II))HEXACYANOCHROMIUM(III) CHLORIDE, [Cr(CN)4 CNNi(tetren) 2]Cl... [Pg.147]

To a solution of tetraethylenepentamine pentahydrochloride (tetren 5HC1, Aldrich) (2.24 g 6.0 mmol) dissolved in 20 mL of water is added 1.21 g of sodium hydroxide (30 mmol, 5 equiv). A solution of nickel(II) chloride hexa-hydrate in 10 mL of water (0.95 g, 4.0 mmol) is then slowly added. The mixture is stirred for 20 min before adding dropwise a solution of potassium hexacyano-chromate(lll) (0.325 g, 1 mmol) in a minimum of water. The solution is left... [Pg.147]

B. HEXAKIS(TETRENNICKEL(II))HEXACYANOCHROMIUM(III) PERCHLORATE, [Cr CNNi(tetren) 6][C104]9... [Pg.148]

Cr CNNi(tetren) 6](C104)9 is a red-purple solid, soluble in water-acetonitrile mixtures where the undissociated heptanuclear entity can be identified by electrospray ionization mass spectrometry. IR spectroscopy shows the presence of a unique /cn band at 2146 cm of the bridging cyano ligand and an intense band of the perchlorate anion at cr = 1090 cm The IR spectrum of the C-enriched compound prepared from K3[Cr( CN)6] displays a /cn band at 2103 cm The compound crystallizes in a trigonal system, space group R3, with parameters a = b = 15.274 A and c = 41.549 A. The magnetic properties indicate a ferro-... [Pg.149]
