[Ti]
Tridentate binding of BH(4)(-) to a zero-valent metal center was found for the first time in [Ti(CO)(4)(eta(3)-BH(4))](-) (shown in the picture), which was obtained from the reaction of the carbonyl metalate anion [Ti(CO)(6)](2-) with BH(3) small middle dotTHF. Displacement of the unusually labile BH(4)(-) anion by a pyrrolyl anion provided the first metal(0) pyrrolyl complex [Ti(CO)(4)(eta(5)-C(4)H(4)N)](-).
