Magnetic order in the quasi-one-dimensional Ising system RbCoCl3

“…Equation ( 2) has been applied successfully in a number of Co 2+ spinchain materials [68], and for RbCoCl 3 we use the value of C extracted from our data to deduce the parameters g = 2.763(1), D/k B = 35.0(2) K and 2J/k B = 162(1) K (with α = 2.74(1)). Both g and D have a well-defined physical meaning and this susceptibility fit provides accurate estimates of their values, which fall well within the ranges expected for Co 2+ chain compounds [64,67,69,70,71]. A physical interpretation for the single value of J extracted from equation ( 2) is more complex, but for RbCoCl 3 we have measured the magnetic interaction parameters to high accuracy by INS [51].…”

“…where A + B = C, the Curie constant, and D is the zero-field splitting parameter. Subsequent modification to include an average g value [67] led to the form…”

Investigating the Structure Directing Properties of Designer 1,8-Naphthalimide and Amphiphilic Sulfonate Anions and Their FeIII Thiosemicarbazone Complexes

“…[11][12][13][14][15][16][17][18][19][20] Typically, this is through inclusion of structure directing groups (SDGs) into the ligand used for coordination, however it is also possible to include such structure directing properties through the use of designer counter ions.…”

Synthesis, characterization and crystal structure of the new pentahydrate of bis(2,2′-bipyridine-κ2 N,N′)(oxalato-κ2 O 1,O 2)nickel(II)

“…The oxalate dianion is well known as a versatile ligand which can adopt a large range of coordination modes Liu et al, 2007;Paredes-García et al, 2011). As a bridging ligand it is able to mediate strong exchange interactions between paramagnetic metal ions separated by more than 5 Å , which is the basis for the synthetic and magneto-structural investigations of these complexes (Keene et al, 2009;Castillo, Luque, Romá n et al, 2001;Chun et al, 2009;Coronado et al, 2008).…”
