2D coordination polymers

The reaction of the dinuclear gold(I) amidinate complex, [Au2(2,6-Me2Ph-form)2], with Hg(CN)2 (1 2 stoichiometry) in THF forms a 2D coordination polymer, [Au2(2,6-Me2Ph-form)2]-2Hg(CN)2 2THF, not the expected oxidative-addition product of the type formed vdth the ylides. White crystals and a yellow powder are formed.

One of the first reports on these materials deals with the reaction of [Rh(CO)2Cl]2 with aromatic diisocyanides to produce two-dimensional (2D) coordination polymers with stacked layer arrangements, as established from their X-ray powder diffraction patterns (Fig. 2).14-16 Related 2D layered... 

The reaction of Cul with 0.5 Eq of L49 in MeCN gave colorless crystals of [(CuI)2 Ge(CH2SPh)4 ]ra 49 (Scheme 26). This 2D coordination polymer is constructed by dinuclear Cu2( i2-I)2 units, which are linked by the...

For all of the samples studied and for particle sizes down to the lowest studied, 150 nm, very similarly shaped SCO transition curves were observed and taken to imply that no significant size effect influenced the SCO process, at least in these particular nano-objects. Nanocrystals of the 3D coordination polymer [Fe(prazine)Pt(CN)4], which displays SCO properties in the bulk, also preserve the same magnetic, structural and optical bistability for particle sizes on the order of 50 nm. Recent evidence suggests however that this may not always be the case, as in the example of the 2D coordination polymer [Fe(3-fluoropyridine)2M(CN)4] where the bulk SCO properties were shown to be very markedly influenced by the nanoparticle dimen-sions. Detailed discussion of this topic falls outside the scope of this review but we refer to it here because it is an aspect of spin crossover studies that bears fundamentally" " on the practical application in device teehnology of nano-dimensioned SCO materials, which continue to display hysteretie behaviour at such dimensions.
