X-RAY DIFFRACTION	5.25	293	Tetragonal shaped crystals amenable to diffraction studies were grown by the hanging drop vapor diffusion method on silanized glass covers slips at 20 C and grew with dimensions routinely exceeding 0.1 x 0.1 x 0.5mm. Gd3+, a competitive inhibitor of Mg2+, has a useful anomalous absorption edge at the CuK wavelength and therefore was used in the co-crystallization or soaking conditions. -Mg2+/+Li+/+Ins(1,3,4)P3/+Gd3+ (data=ip7r): Reservoir solution consisted of 10% PEG 8000, 80mM Bis-Tris, pH 5.25, 2mM Gd2(SO4)3, 1mM Ins(1,3,4)P3; 200mM Li2SO4
