The crystal structure of meglumine diatrizoate has been solved and refined using synchrotron X-ray powder diffraction data optimized density functional theory techniques. Meglumine crystallizes in space group P2 1 (#4) with a = 10.74697(4), b 6.49364(2), c 18.52774(7) Å, β 90.2263(3), V 1292.985(5) Å 3 , Z 2. Two different structures, which yielded essentially identical refinement residuals pos...

Crystals of Pb3Mn7O15 doped with titanium ions have been synthesized. The study the structural properties showed that occupy positions in “columns” between planes, which leads to a weakening exchange interaction planes. temperature dependences magnetization and heat capacity revealed two anomalies at 62 K 35 K. At K, long-range magnetic order presumably appears, spin-reorientation transition oc...
