“…This is atypical for transition metal hexacyanometallates. As already‐mentioned, such coordination has also been reported for Sn 2 [Fe(CN) 6 ] and Pb 2 [Fe(CN) 6 ] . In this study we are comparing the XPS spectra recorded for T 2 [M(CN) 6 ] with M = Fe, Ru, Os, and TK 2 [Fe(CN) 6 ] · x H 2 O in order to explore the capability of this technique as a sensor to discriminate between linear or bifurcated coordination of the CN ligand.…”

“…When T = Co 3+ , it adopts a low spin electronic configuration in order to favor the complex salt stability . The formation of linear ··· T–N≡C–M–C≡N–T ··· bridges, is the common coordination mode for the CN ligand, but there are several compositions where it appears coordinated to two T metals, in a bifurcated coordination mode , . The valence, electronic configuration, and coordination number of the involved metal and coordination mode for the CN ligand are relevant features for the above mentioned potential applications of this family of coordination polymers.…”

This study reports an evaluation on the scope of X‐ray photoelectron spectroscopy (XPS) to obtain information for the coordination chemistry of transition metal (Tn) hexacyanometallates, TxAz[Mm(CN)6]y where nx +z = y(6 – m), A is an alkaline charge‐compensating cation, and Mm is a transition metal with a maximum of 6 electrons in its nd orbitals. XPS provides an elegant picture on the role of the CN π‐back bonding effect to determine the charge density on the N atom and, from this fact, on its coordination to transition metal ions to form coordination polymers. XPS appears to be able to discriminate between octahedral and tetrahedral coordination for the outer metal (T) to the N end of CN ligands, particularly when the XPS peak and the Auger lines are combined. A similar performance was observed when this spectroscopic technique is used to identify when the CN ligand is found with linear and bifurcated coordination mode to the metal linked at its N end. These last two structural features are relevant in the coordination of metal hexacyanometallates and determine their physical and functional properties. The results obtained from XPS data were correlated with the a priori information from IR spectra and the reported crystal structures for all the samples under study.

“…It should be mentioned that, due to the lack of accurate information on anhydrous Na 4 Fe(CN) 6 compounds in existing crystallographic databases and published documents, we cannot describe the detailed crystal structure of the Na 4 Fe(CN) 6 lattice. However, by analogy with similar anhydrous hexacyanoferrates such as K 3 Fe(CN) 6 and K 3 Co(CN) 6 22 and H 3 Fe(CN) 6 and Sn 2 Fe(CN) 6 ,23 we can speculate that the dehydrated Na 4 Fe(CN) 6 lattice should remain in a layered structure consisting of Fe(CN) 6 −4 groups with Na ions placed in the interlayer area after removal of H 2 O.…”

“…Apparently, such N species need to be covalently stabilized like in the azide anions of Pb(N 3 ) 2 . This kind of covalent stabilization can also be realized by C−N bonds as known from ferrocyanides, thiocyanates, cyanamides, dicyanamides, tricyanomethanides, and organolead(II) amides . A similar effect is found for compounds where N is bound to the trimethylsilyl protecting group (‐SiMe 3 ) to form trimethylsilylamides .…”

Cationic Pb₂ Dumbbells Stabilized in the Highly Covalent Lead Nitridosilicate Pb₂Si₅N₈

Due to the weak oxidative force of N2, nitrides are only typically formed with the less electronegative metals. Meeting this challenge, we here present Pb2Si5N8, the first nitridosilicate containing highly electron‐affine cations of a metal from the right side of the Zintl border. By using advanced synchrotron X‐ray diffraction, the crystal structure was determined from a tiny single crystal of 1×3×3 μm3 in size, revealing a significantly different bonding situation compared to all other nitridosilicates known so far. Indeed, DFT calculations confirm distinct amounts of covalency not only between Pb and N but also between formal Pb2+ cations. Thus, unprecedented cationic Pb2 dumbbells with a stretching vibration at 117 cm−1 were found in Pb2Si5N8, the first representative of a crystallographically elucidated lead nitride, stabilized by high amounts of covalency.
