Two ions isoelectronic with carbon suboxide, C₃O₂ , are and OCNCO⁺ . Whereas C₃O₂ is linear, both and OCNCO⁺ are bent at the central nitrogen. Suggest an explanation.

Also predict which has the smaller outer atom—N—outer atom angle and explain your reasoning. (See I. Bernhardi, . Drews, K. Seppelt, Angew. Chem., Int. Ed., 1999 , 38 , 2232; K. O. Christe, W. W. Wilson, J. A. Sheehy, J. A. Boatz, ngew. Chem., Int. Ed ., 1999 , 38 , 2004.)
