A new ternary compound Cu2SnTi3 has been synthesized by vacuum sintering at 900 °C. The atomic structures of CaCu5- and InNi2-like Cu2SnTi3 are calculated using density functional theory methods. The X-ray diffraction (XRD) analysis and selected area diffraction (SAD) patterns of the new ternary compound Cu2SnTi3 are considered to verify the atomic structures of CaCu5- and InNi2-like Cu2SnTi3. The results reveal that the InNi2-like Cu2SnTi3 model has the lowest total energy of −35.239 eV, representing the trigonal crystal structure. The orthorhombic crystal structure of the CaCu5-like Cu2SnTi3 model has the second lowest total energy of −33.926 eV. Our theoretical X-ray diffraction peak profiles of InNi2-like (CaCu5-like) Cu2SnTi3 are nearly identical to experimental one, leading to an error below 2.0% (3.0%). In addition, the hexagonal crystal structure of the CaCu5-like Cu2SnTi3 model has the highest total energy of −33.094 eV. The stability of the Cu2SnTi3 in terms of energy follows the order: the trigonal, orthorhombic, and hexagonal crystal structure.

A new ternary compound Dy5Co6Sn18 was synthesized and studied. The crystal structure of Dy5Co6Sn18 was determined using the Rietveld refinement method. The compound was found to crystallize in tetragonal space group I41/acd, Tb5Rh6Sn18-type structure, with a=13.5598(3) Å, c=7.1470(5) Å, Z=8, and Dcalc=8.789 g/cm3. Measurements of magnetic susceptibility and electrical resistivity on polycrystalline samples were also performed. The Curie–Weiss law was followed, with θp=−15.7 K and μeff=10.61μB. Dy5Co6Sn18 is a spin-glass with a freezing temperature of 6.5 K.

Bis(1,2-diammoniopropane) hexachlororhodate(III) chloride, [H3N-CH(CH3)-CH2-NH3]2 [RhCl6]Cl (1) has been obtained by the reaction of rhodium(III) chloride with rac-1,2- diammoniopropane dihydrochloride in hydrochloric acid solution. The quasi-ternary compound, which crystallizes in the orthorhombic space group Pbca (a - 11.0007(13) Å, b = 22.181(2) A, c = 14.638(2) A, V = 3571.7(7) Å3, \ T = -120 °C, Z - 8) contains two crystallographically independent 1,2-diammoniopropane ions beside one hexachlororhodate and one chloride ion. One of the cations shows a R/S-S/R-disorder of enantiomeric pairs in the centrosymmetric crystal lattice. The packing scheme is determined by a complex framework of hydrogen bonds.
