The reaction of SnCl 2 with the Janus Head ligands Ph 2 PPic ( 1 , Pic = 2‐picolyl) and Ph 2 P(NSiMe 3 )Pic ( 2 ) led to the novel tin complexes [(Ph 2 PPic)Sn(Cl)][SnCl 3 ] ( 4 ) and [(Cl) 2 Sn{(NH)(Pic)PPh 2 }]·THF ( 6 ). The hemilability of the Ph 2 PPic ( 1 ) ligand in 4 was investigated by low temperature 119 Sn and 31 P NMR studies. A remarkable equilibrium of two formal SnCl 2 units with 1 could be revealed. Crystal structure analysis of 4 and 6 substantiated the understanding of the hemilabile behaviour of the presented Janus Head ligands.
