The third example of an organogallium four-membered ring compound with arsenic, halogen mixed bridging, Me3SiCH22GaAsSiMe32GaCH2SiMe32CI, was prepared by the reaction of Me3Si3As with two equivalents of Me3SiCH2 2GaC1. X-ray crystallographic analysis showed that the compound contains a nonplanar Ga-As-Ga-C1 ring. The crystals belong to the monoclinic system space group P21c C52h with four molecules per unit cell of dimensions a 12.476, b 15.832, c22.279 A, Beta 108.87, V 41642 A3. The dimer Me3SiCH22GaAsSiMe322 was prepared by reaction of LiAsSiMe32 and Me3SiCH22GaC1. Its solid-state dimeric structure was established by single-crystal X-ray analysis.
