Structural analyses of two hexacyanoruthenate(II) complexes

Tuning the metal-to-metal charge transfer energy of cyano-bridged dinuclear complexes

“…21,22 The coordinate bonds around the Ru atom are the same within experimental error and consistent with those found in other hexacyanoruthenate(II) containing structures. [24][25][26] A notable feature is the pronounced distortion of the C1a-N1a-Co angle (162.8(8)°) from its ideally linear value. Examination of the crystal packing (ESI Fig S1 †) illustrates that this distortion can be attributed to repulsion between the Co pentaamine fragment and the tetrahedrally coordinated Na atom (which is also coordinated to the cyano ligand through N4a).…”

Gadolinium Potassium Hexacyanoferrate(II) Trihydrate

“…As a result, the occupancy factors for the zeolitic water molecule and the potassium ion are set at 0.5. The LnKRu(CN)6 series also display a phase transition from the hexagonal form (Mullica, Hayward & Sappenfield, 1996a) to the orthorhombic C-centered structure (Mullica, Hayward & Sappenfield, 1996b). In the orthorhombic lanthanide potassium hexacyanoruthenates, however, the potassium ion and zeolitic water molecules occupy specific crystallographic sites with no disorder.…”

“…In the orthorhombic lanthanide potassium hexacyanoruthenates, however, the potassium ion and zeolitic water molecules occupy specific crystallographic sites with no disorder. The structural investigation of gadolinium potassium hexacyanoferrate was initiated in order to determine whether the K ÷ ion and zeolitic H20 occupy separate crystallographic sites as in the gadolinium and terbium potassium hexacyanoruthenates (Mullica, Hayward & Sappenfield, 1996b).…”

“…Gadolinium hexacyanoferrate(llI) and gadolinium hexacyanoruthenate(III) crystallize in the orthorhombic C-centered space group Cmcm Mullica, Hayward & Sappenfield, 1996b). On the other hand, gadolinium potassium hexacyanoferrate(II) trihydrate crystallizes in the primitive space group Pnma (No.…”

A New Family of Bimetallic Framework Materials Showing Reversible Structural Transformations

“…The environment of the topological nodes is shown in Figure S6 The RusC and C-N bond distances and CsRusC angles are in good agreement with published values. [61][62][63][64] The Cu II ion is penta-coordinated, bonding to two nitrogen atoms of two equivalent tn ligands (N4, N5), and to three nitrogen atoms of the cyano groups (N1, N2 and N3). The NsCusN angles in the pseudo base deviate strongly from ideal trigonal-bipyramidal geometry ( Figure 6).…”
