Synthesis and Characterization of Chromium Tricarbonyl Complexes of 1-Phenylgermatrane and 1-Phenylazagermatrane. Crystal Structure of [N(CH₂CH₂O)₃GeC₆H₅]Cr(CO)₃

The reaction of 1-phenylgermatrane (1) and 1-phenylazagermatrane (2) with Cr(CO) 6 affords chromium tricarbonyl complexes [N(CH 2 CH 2 O) 3 GeC 6 H 5 ]Cr(CO) 3 (6) and [N(CH 2 - CH 2 NH) 3 GeC 6 H 5 ]Cr(CO) 3 (7). In contrast, the same reaction of Cr(CO) 6 with 1-(9-anthracenyl) germatrane (3) does not proceed. Composition and structures of the 6 and 7 were established by elemental analyses, 1 H and 13 C NMR spectroscopy and mass spectrometry. The crystal structure of 6 is reported
