The neutron diffraction study of Atoji (1981b) on the crystal and magnetic structures of the cubic ErCo.6 compound in the temperature range 1.6-296 K confirmed the previously reported results (Spedding et al. 1958, Lallement 1966). Its cubic structure is illustrated in fig. 9, in trigonal coordinates in order to compare it with the trigonal structure of R2C (Atoji and Kikuchi 1969).

There are several comprehensive textbooks and review articles devoted to organic superconductors [3,4,182-186] which describe design and preparation, crystal and band structures, chemical, transport, magnetic, optical, and thermal properties, and theory.

The electronic properties of binary and ternary intermetallic Zintl phases crystallizing in the NaTl type of structure are investigated and reported. The crystal and defect structure, the electronic band structure and density of states, the bonding mechanisms and the charge transfer are discussed. Comparison is made between the electronic states in the B2 and the B32 types of structure. Furthermore, based upon theoretical studies of the electronic valence states the optical properties (imaginary part of the dielectric constant and reflectivity) and the magnetic properties (susceptibility and Knight shift) are considered. 

The problem encountered here is rather different. The Cu(II)—Mn(II) dithiooxalato chain (CuMnDTO 7.5 H O) is obtained at room temperature under the form of single crystals and the structure of the pure product is fully characterized, without any disorder (Fig. 20). It is the first ID compound to present the ferrimagnetic behaviour shown in Fig. 21 curve 1. However, the partially dehydrated compound CuMn— (Cj0282)2 3 H2O, obtained at higher temperature, presents no longer ferrimagnetic properties (Fig. 21, curve 2) and its structure is not known. It exists intermediate hydrated materials where the magnetic properties are also very different from the fully hydrated material (Fig. 21, curve 3).

A number of the properties of g-oxo dimers of Fe porphyrins, formed by hydrolysis of the hydroxo complex (equation 17) or by reaction of molecular oxygen with Fe porphyrins (see below), have been investigated, including H and C NMR, IR and Raman, and Mossbauer spectra, magnetic susceptibilities, and crystal and molecular structures.
