Hi Mike, good to hear from you!  I'll do some digging and see if I have anything more on your compound.  Somewhere around here I've even got an old pre-1991 edition of Jolly too - it's been a standard text for I don't know how long.

One of our General Chem II labs is "Colorimetric Determination of Iron", in which the students take a sample containing an unknown amount of iron(III), reduce it to iron(II) with hydroxylamine, and add excess o-phenanthroline to form the dark-red product.  This absorbs very strongly at 510 nm, which they measure with a Spec 20, and with a Beer's Law plot they then determine the amount of iron in their sample.  This is a good experiment except that the o-phenanthroline is costly.

L8R!

Steve
