%X The title compound, [{(Me3Si)2NCH2}2], has been structurally characterized by a single-crystal X-ray structure determination at 130 K, being refined by full-matrix least-squares to a residual of 0.057 for 1244 'observed' reflections. Crystals are monoclinic, C2/c, a 21.00(2), b 9.089(8), c 11.744(9) &#506;, &#946; 92.31(7)&#176;, Z 4. Molecules lie on inversion centres, but with some disorder of the methylene groups. Si -N are 1.735 &#506;, and N-CH2 1.53(1) for the major fragment (70%). The nitrogen in the major fragment is approximately trigonal planar; Si -N- Si 124.6(3)&#176;, Si -N-C 117.5(4), 115.5(4)&#176;.
