A novel low‐temperature liquid phase synthesis of the Sn0 nanoparticles has been reported. The effect of different reducing agents (Li[AlH4], K[BEt3H], Na[BH4]) on the reduction of the two different N,N‐coordinated SnII complexes has been described. The influence of the different imino‐pyridine chelating ligands to the synthesis of the Sn0 particles, their separation and the usage of surfactant for resuspendation to nanocolloid has been studied. The Sn0 nanoparticles were studied by means of Energy‐dispersive X‐ray spectroscopy, powder X‐ray diffraction, atomic force microscopy and dynamic light scattering from the point of view of the chemical composition, crystallinity and size/agglomeration behavior.
