摘要	Featuring an extra electron in the pi* antibonding orbital, species with a 2-center-3-electron (2c3e) pi bond without an underlying sigma bond are scarcely known. Herein, we report the synthesis, isolation and characterization of a radical anion salt [K(18-C-6)](+){[(HCNDipp)(2)Si](2)P-2}& sdot;(-) (i.e. [K(18-C-6)](+)3 & sdot;(-)) (18-C-6=18-crown-6, Dipp=2,6-diisopropylphenyl), in which 3 & sdot;(-) features a perfectly planar Si2P2 four-membered ring. This species represents the first example of a Si- and P-containing analog of a bicyclo[1.1.0]butane radical anion. The unusual bonding motif of 3 & sdot;(-) was thoroughly investigated via X-ray diffraction crystallography, electron paramagnetic resonance spectroscopy (EPR), and calculations by density functional theory (DFT), which collectively unveiled the existence of a 2c3e pi bond between the bridgehead P atoms and no clearly defined supporting P-P sigma bond.
