In this work we report synthesis and
crystal structure of compounds La6Co13In, La5-δCoxIn3-x
and La3CoxIn1-x. From X-ray single crystal
data: La6Co13In crystallizes in the structure type of Nd6Fe13Si,
I4/mcm, Z=4, a = 8.1190(4), c = 23.7022(15)
Å; La5-δCoxIn3-x in the tetragonal
structure type of W5Si3, I4/mcm, Z = 4, a = 12.9644(3),
c = 6.1553(2) Å at δ = 0.125(15) and x = 0.06(3), and a = 12.9976(5), c = 6.1229(7) Å at δ = 0.275(15) and
x = 0.10(3), La3CoxIn1-x is the
solid solution of Co in La3In, which crystallizes in the cubic
structure type of Cu3Au, Pm-3m, Z=1, a = 5.0762(1) Å at x = 0.05.
