“…The C---Ge bond lengths [1.929 (5)-1.942 (7) A] are within the range of C(sp3)--Ge bond lengths [1.933 (6)-1.967 (3)A] previously reported for germacyclanes (Faucher, Mazerolles, Jaud & Galy, 1978;Preut, Krcher & Neumann, 1985;Sommese, Cremer, Campbell & Thompson, 1990). All the C---C--C angles (2) (Takeuchi, Shimoda, Tanaka, Tomoda, Ogawa & Suzuki, 1988), except for the bond angle Cring-----Gc ¢-~ for "~ring, which the calculation gave a significantly smaller value (101.9°).…”
