Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 20759-14-2, Cl3H2ORu.

The complexes, [Ru(bdmpp)(bpy)Cl](PF6) (1a), [Ru(bdmpp)(phen)Cl](PF6) (2a), and [Ru(bdmpp)(Me2bpy)Cl](PF6) (3a) (where bdmpp is 2,6-bis(3,5-dimethyl-N-pyrazoyl)pyridine, bpy is 2,2?-bipyridine, phen is 1,10-phenanthroline and Me2bpy is 4,4?-dimethyl-2,2?-dipyridyl) were synthesized and characterized by 1H NMR, electronic absorption spectroscopy and cyclic voltammetry. 1a and 3a were also characterized by X-ray crystallography. The chloride salt of 1a, [Ru(bdmpp)(bpy)Cl]Cl · 1.25CHCl3, crystallizes in the monoclinic space group P21/n with Z=4, a=13.551(2), b=8.556(1), c=29.994(3) A, beta=100.28(1), V=3421.8(7) A3 with 4486 unique data yielding R1=0.0715 (I2sigma(I)). The chloride salt of 3a crystallizes in the triclinic space group P1 with 1.25 chloroform solvate and a=8.656(1), b=10.685(2), c=18.729(3) A, alpha=94.394(6), beta=99.72(1), gamma=98.61(1), V=1679.0(4) A3, Z=2, and R1=0.066 (I2sigma(I)) with 4403 unique reflections. Compounds 1a, 2a, and 3a are converted to their corresponding aqua complexes, 1b, 2b, and 3b upon treatment with aqueous silver ion, and to the acetonitrile species, 1c, 2c, and 3c, by dissolution in acetonitrile. Cyclic voltammograms in acetonitrile of 1a, 2a, and 3a display one-electron oxidations at 0.72, 0.71, 0.63 V, respectively, consistent with a Ru(III/II) couple. Compounds 1b, 2b, and 3b show a pH independent couple at pH<2 and a pH dependent couple consistent with a one-electron, one-proton process at pH values from ca. 2 to 11. Past pH 11 this redox process becomes pH independent again, and the compounds become unstable. The one-electron nature was verified by bulk electrolysis and spectroelectrochemical measurements.
