Abstract
The reaction of NHEt2 with CO2 and chlorinated chromium(II) substrates yielded Cr2(O2CNEt2)4(NHEt2)2 identical with the product obtained by a different route. The dichloride beta-MoCl2 reacts with the NHEt2/CO2 system to give Mo2(O2CNEt2)4 in good yields. Crystal data: M(r) = 658 .4; triclinic; space group P1; a = 9.217(3), b = 9.613(3), c = 8.852(3 ) angstrom; alpha = 95.46(3), beta = 104.66(3), gamma = 63.12(3)degree s; V = 676.6 angstrom3; Z = 1; D(c) = 1.610 g cm-3. Each molybdenum at om in a square pyramidal geometry is surrounded by four carbamato oxyg ens, the Mo-Mo distance of the quadruply bonded system being 2.067(2) angstrom.
