From the reviews:

"The e-book succeeds at providing the variety of methods required and used to appreciate and make the most single-molecule magnets (SMMs) … . The references are exhaustive … . accordingly on my own it'd be a good suggestion to have this publication to be had within the laboratory. … total, this publication is an effective selection of the paintings that has been performed within the box of SMMs." (Matthew P. shorelines, magazine of the yankee Chemical Society, Vol. 129 (12), 2007)

From the stories:

"In one feel, the ebook succeeds at offering the diversity
of ways required and used to appreciate and exploit
SMMs, be they chemical, actual, fabrics orientated, or
theoretical. nevertheless, the booklet is ruled by way of the
Mn12 cluster, the 1st species characterised as a single-molecule
magnet. this can be rarely superb, because the cluster additionally displays
the optimum stated reorientation barrier in an isolable species.
The bankruptcy on spectroscopy focuses basically on Mn12 and Fe8,
while the essay referring to incorporation of SMMs into new
materials in simple terms makes use of examples during which Mn12 is involved.

The references are exhaustive and competently disguise the field
to the center of 2005. accordingly on my own it might be a good
idea to have this publication to be had within the laboratory. With the
burgeoning curiosity within the box, notwithstanding, it really is transparent that an
update can be wanted quickly. total, this e-book is a good
collection of the paintings that has been performed within the box of SMMs"

It might be superfluous to emphasize the significance of digital . spectroscopy in structural or analytic examine. It has now develop into an issue of regimen to checklist the ultra-violet or noticeable spectra of compounds for reasons of id or constitution elucidation. The spectrophotonletric equipment of research have changed the traditional equipment in ever so rnany situations.

Hydrogen atoms are omitted for clarity. Code for atoms as in Fig. 37 as citric acid [173]. Among the compounds with Ni(II) is 66 [174], one of the largest Ni clusters known [175]. The structure (Fig. 39) contains a planar central unit [Ni7 (µ3 – OH)6 ], similar to that seen in a layer of Ni(OH)2 , and comparable with that found in [Fe19 ] [138] or [Co24 ] [176] clusters. Twelve bridging citrate ligands in five different binding modes link the remaining metal centres to this unit. Cluster 66 displays two chiral centres on Ni(II) atoms at both ends of the molecule.

Code for atoms as in Fig. 8 [Fe9 O4 (OH)5 (heia)6 (Hheia)2 ] (60); A Piece of All-Ferric Molecular Magnetite The cluster [Fe9 O4 (OH)5 (heia)6 (Hheia)2 ] (60, Fig. 36) [160] was prepared in methanol from Fe(NO3 )3 · 9H2 O and H2 heia in the presence of tetramethyammonium hydroxide. The structure features a central tetrahedral Fe(III) ion bound by four µ3 – O2– groups to eight peripheral octahedral ferric centres.

This molecule (Fig. 33) comprises two groups of four Fe(II) centres, linked via a central Fe(II) by four pdol2– ligands. Within each group, the Fe(II) atoms are bridged by a rare µ4 – N3 – ion and four µ2 – OAc– ligands. This complex was prepared from the structurally related cluster [Fe9 (OH)2 (O2 CMe)8 (pdol)4 ] Fig. 33 PovRay representation of [Fe9 (N3 )2 (O2 CMe)8 (pdol)4 ] (56). Hydrogen atoms are omitted for clarity. Code for atoms as in Fig. 29 42 G. K. Brechin (57) via the selective replacement of two µ4 – OH– ligands by µ4 – N3 – groups.
