Establishing a congruent approach to delivering a pnictide atom (Pn3- = P, As, and Sb) to transition metal ions is a challenge, especially for the heavier congeners As and Sb, and when varying the transition metal. We showcase here a convenient route to molecular forms of one coordinate stibide ligands bound to ZrIV and TiIV ions, represented by the discrete salts [K(L)][(PN)2M≡Sb] (M = Zr (2), Ti (10); PN- = (N-(2-PiPr2-4-methylphenyl)-2,4,6-Me3C6H2; L = 2,2,2-Kryptofix or 18-C-6 crown-ether/2THF), which were prepared via H2 extrusion from [K(18-C-6)(THF)SbH2] added to the ZrIV cyclometallated-hydride, [(PN)(PN')Zr(H)] (1), and the TiII precursor [K(18-C-6)][(PN)2TiCl] (8) respectively. This strategy was extended to the lighter congeners Pn = As, P using [K(18-C-6)(THF)AsH2] (M = Zr (3)), and NaPH2 (M = Ti (6)). Structural and computational studies were applied to understand the bonding trends in the pnictide series, and the role of the metal ion.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
