Tridentate binding of BH 4 − to a zero‐valent metal center was found for the first time in [Ti(CO) 4 ( η 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 ⋅THF. Displacement of the unusually labile BH 4 − anion by a pyrrolyl anion provided the first metal( 0 ) pyrrolyl complex [Ti(CO) 4 ( η 5 ‐C 4 H 4 N)] − .
