N2 - The ternary compound Ca4Al3Mg was successfully synthesized by induction melting of appropriate amounts of pure metals followed by annealing at 773 K for 14 days. The crystal structure was determined by X-ray powder diffraction. Ca4Al3Mg crystallizes in space group Pbcm (No. 57); cell parameters: a = 6.1792(1) Å, b = 24.2113(5) Å, c = 5.8864(1) Å; Z = 4. This structure can be built up of the alternating layers of two types of chains. The first type of chains consists of Al 3 triangles sharing one corner and the second one contains AlMg 2 triangles sharing one of the Mg corners. Both of them run along the crystallographic c-axis, forming atomic layers normal to the b-axis.
