The Tetracyanoborate Anion as Building Block for the Heterocubane Cluster Cage [Cr4{B(CN)4}4]4– The tetracyanoborate anion [B(CN)4]– (TCB) was utilized as a building block for the synthesis of polynuclear chromium carbonyl compounds upon photolytic reaction with [Cr(CO)6]. Up to four κN-coordinated cyano groups of TCB can be involved in binding to chromium, giving mixtures of [B(CN)4–x{CN–Cr(CO)5}x]− (x = 1–4; 1–4) and [{Cr(CO)4(B(CN)4)}2]2– (5).
