eng	Stabilization of two coordinate tetrylene by borylamide ligand	Here we report the synthesis of aminoborane HN(BCy2) (C6H3-2,6-Me-2) (1) (Cy = cyclohexyl), that was successfully deprotonated and its lithium salt {LiN(BCy2) (C6H3-2,6-Me-2)}(2) (2) has been characterised. The borylamide ligand -N(BCy2) (C6H3-2,6-Me-2) was used for the preparation of N -> Sn coordinated stannylene [2,6-(Me2NCH2)(2)C6H3]Sn [N(BCy2) (C6H3-2,6-Me-2)] (3) and two coordinate tetrylenes {E [N(BCy2) (C6H3-2,6-Me-2)](2)} (E = Sn (4), Pb (5)). Experimental and theoretical studies suggested sigma character of E-N bonds without additional N(p)-> E(p) donation as the result of the preference of N(p)-> B(p) donation in 4 and 5. DFT studies on 4 and 5 also reveal theirs HOMO to exhibit E lone pair character and theirs LUMO to include p-orbital character located on metal atoms E. (C) 2018 Elsevier B.V. All rights reserved.
