Using X-ray diffraction technique and transmission electron microscopy it has been demonstrated that multiphase Sn–Ni electrodeposits with 3–34 at.% Ni contain a new phase of composition close to NiSn
9. Its lattice parameters are specified as follows:
a
0 = 1.2621(7),
b
0 = 0.5231(4),
c
0 = 0.6213(4) (in nm),
= 105.8(7)° of the C 2/m space group. This new phase decomposes at 100°C into
tin and Ni
3Sn
