摘要：

Heavy Metal π Complexes, V1. ‐ The Layer Polymer {([C6H6SnCl][GaCl4])2}x,y In the system C6H6/SnC12/GaC13 crystalline (benzene)chlorotin(+2) tetrachlorogallate(+3) (1) is obtained. According to an X‐ray structure analysis (Pca21) the solid contains polymeric {([C6H6SnCl][GaCl4])2}x,y layers built up by ((C6H6SnC1][GaCl4])2 structural units. A unit consists of an Sn2Cl22+ four‐ membered ring, two GaCl4− tetrahedra at opposite sides of the ring plane, and two benzene molecules bound to the tin atoms in a distorted η6 state. A pseudorotational disorder of one of the benzene ligands was found. The tin‐arene bonding is much weaker in 1 compared to the chain polymer (([C6H6SnCl](AICl4])}x(2).
