Manganites NdM 3 Sr 3 Mn 4 O 12 and NdM 3 Ba 3 Mn 4 O 12 (M = Li, Na, K) were synthesized by a ceramic method from the corresponding oxides and carbonates. The X-ray diffraction analysis showed that all the compounds crystallized in the tetragonal crystal system with the following lattice parameters: NdLi 3 Sr 3 Mn 4 O 12 : a = 10.88 Å, c = 9.52 Å, V o = 1126.9 Å 3 , Z = 4, ρ X = 4.95 g/cm 3 , ρ pycn = 4.87 ± 0.05 g/cm 3 ; NdNa 3 Sr 3 Mn 4 O 12 : a = 10.73 Å, c = 10.66 Å, V o = 1227.3 Å 3 , Z = 4, ρ X = 4.80 g/cm 3 , ρ pycn = 4.73 ± 0.07 g/cm 3 ; NdK 3 Sr 3 Mn 4 O 12 : a = 10.87 Å, c = 11.71 Å, V o = 1382.6 Å 3 , Z = 4, ρ X = 4.50 g/cm 3 , ρ pycn = 4.43 ± 0.09 g/cm 3 ; NdLi 3 Ba 3 Mn 4 O 12 : a = 10.97 Å, c = 10.34 Å, V o = 1244.3 Å 3 , Z = 4, ρ X = 5.33 g/cm 3 , ρ pycn = 5.23 ± 0.09 g/cm 3 ; NdNa 3 Ba 3 Mn 4 O 12 : a = 10.99 Å, c = 11.15 Å, V o = 1346.7 Å 3 , Z = 4; ρ X = 5.11 g/cm 3 , ρ pycn = 5.05 ± 0.06 g/cm 3 ; NdK 3 Ba 3 Mn 4 O 12 : a = 10.997 Å; c = 13.80 Å, V o = 1668.9 Å 3 , Z = 4, ρ X = 4.32 g/cm 3 , ρ pycn = 4.26 ± 0.07 g/cm 3 .
