more bulky stannylenes (e.g. lappert's stannylene), on the other hand, tend to form a dimer. the nature of the sn-sn bond in stannylene dimer is rather different from c-c bond in carbene dimer (i.e. alkene). as alkene develops a typical double bond character and the molecule has a planar geometry, stannylene dimer has a trans-bent geometry. the double bond in stannylene dimer can be considered as two donor-acceptor interactions. the electron localization function (elf) analysis of stannylene dimer shows a disynaptic basin (electrons in bonding orbitals) on both sn atom, indicating that the interaction between two sn atom is two unusual bent dative bonds. apart from that, the stability of stannylene dimer is also affected by the steric repulsion and dispersion attraction between bulky substituents. br
