The first four-membered ring containing two indium atoms with bridging by two different group 15 elements, Me3SiCH22InAsSiMe32InCH2SiMe3 2PSiMe32 1, to be characterized completely was prepared by the equilibration of Me3SiCH22InPSiMe322 2 with Me3SiCH22InAsSiMe322 3 in a 11 mole ratio. X-ray crystallographic analysis showed the In-As-In-P ring of 1 to be planar. Crystals of 1 belong to the orthorhombic system, in the space group Pbcn D142h, with four molecules in a unit cell of dimensions a 12.848 1 A, b 21.558 1 A, c 18.736 1 A, and are isomorphous with those of 2 and 3. The electron ionization 20 eV mass spectrum of 1 shows a fragmentation pattern indicative of this compound and no peaks 510 mz consistent with either 2 or 3. Clusters assigned to specific ions in the mass spectrum show appropriate isotopic patterns as calculated for the atoms present.
