description The symmetric title mol­ecule, [Hf(C(26)H(40)N(4)Si)Cl(4)], lies about a twofold rotation axis. The Hf(IV) and Si atoms lie on the rotation axis with all other atoms being in general positions. The Hf(IV) atom is six-coordinated by two N atoms from the N (2),N (2′)-(di­methyl­silanedi­yl)bis­(N-tert-butyl-3-methyl­benz­imid­amidate) ligand and four Cl(−) ions in a slightly distorted octa­hedral geometry. The two amidinate moieties are connected through the central Si atom with Si—N bond length of 1.762 (3) Å, generating the characteristic N—C—N—Si—N—C—N skeleton of a silyl-linked ansa-bis­(amidine) species.
