guarded optimism

The crystals I sent the X-ray lab seem to have held up in the mounting oil and diffracted well enough. The strong scattering (shown in the picture) and unit cell dimensions indicate some sort of monomer with one heavy atom (the metal atom) per unit cell. I don't have the solved structure in hand yet, but I'm ready to declare victory as far as getting a quality crystal. I've seen better, these were pale orange needles. Not too shabby though.

X-ray quality crystals were grown from a standing cooled solution in heptane over several weeks at a temperature of -35 C.
