The first Ti 4 Si 4 heterocubane with twelve edges bridged by O atoms was prepared in good yields and characterized by X‐ray crystallography. According to the IR spectrum of 1 , the characteristic band for Ti‐containing zeolites at approximately 960cm −1 , the assignment of which had been debated, arises from the SiOTi stretching vibration. R 1 = t Bu, t Bu 3 C 6 H 2 O, i Pr 2 C 6 H 3 N(SiMe 3 ); R 2 ‐ MeC 5 H 4 , O i Pr.
