A crystal structure study when crystallized only in d(CG)3 + methylamine and a d(CG)3 + metal ion.

There is not an example of the crystallization only of d(CG)(3) and a metallic cation without putting the amine in addition in there is no example of the crystallization d(CG)(3) with methylamine that is the mono-amine so far either. We were able to obtain a very beautiful crystal with all sides of 0.3mm by the sitting drop method that had done the crystallization of d(CG)(3)+ methylamine and d(CG)(3)+ Mg(2 +). The crystal was diffracted up to 1.0 A by using the synchrotron radiation. As a result of the X-ray crystal structure analysis, methylamine was not seen while d(CG)(3)+ methylamine was crystallizing mysteriously. d(CG)(3) had stabilized with five Mg(2+) ions. d(CG)(3) had stabilized similarly with five Mg(2+) ions in the crystal of d(CG)(3)+ Mg(2+). The position of these five Mg(2+) ions understood that I agreed on superimpose in a crystal of d(CG)(3) + methylamine, a crystal of d(CG)(3)+Mg(2+), a crystal of d(CG)(3) + spermidine, and crystals of d(CG)(3) + PA (24) which was already analyzed so as to cut it and stabilized d(CG)(3) at an about the same position.
