“…Figure 5a, b presented the Raman spectra of (C 7 H 18 N 2 )CuCl 4 crystals recorded at room temperature. The Raman spectra consist of wellseparated peaks that can be subdivided into two main groups .A detailed assignment of all the bands is difficult, but we can attribute some of them by comparison with similar compounds [6,20,21]. The assignments of the bands observed in the infrared and Raman spectra of [C 7 H 18 N 2 ] CuCl 4 are listed in Table 5.…”

“…The materials based upon substituted complex ammoniums with halogenated metals such as Hg, Cd, Zn, and Cu present very interesting physical properties [3,4] The magnetic susceptibility is an important tool for the magnetic characterization of the materials. One of the best studied groups, both in solution and the solid state, are the halocuprate complexes [5,6]. The large structural variability of Cu (II) due to the presence of an active Jahn-Teller effect in the d 9 electronic system and the relative flatness of the potential surfaces make the thermochromism in chlorocuprates of continual interest.…”

Synthesis, crystal structure, vibrational study and magnetic properties of the compound (C 7 H 18 N 2 ) CuCl 4 are reported. The latter crystallizes in the monoclinic system (space group P2 1 , Z = 4) with the following unit cell dimensions: a = 7.569(5)Å b = 14.174(5)Å, c = 13.193(2)Å and β = 105.53(3) • . Besides, its structure was solved using 5754 independent reflections down to R = 0.0475. The atomic arrangement can be described by alternating organic and inorganic layers stacked in the [101] direction, made up of tetrahedral of tetrachlorocuprate CuCl 2− 4 sandwiched between two organic layers. In crystal structure, the inorganic layer, built up by independent monomeric [CuCl 4 ] 2− , is connected to the organic ones through hydrogen bonding in order to build a threedimensional network. The magnetic behavior of (C 7 H 18 N 2 ) CuCl 4 samples was investigated as a function of temperature and applied field. At hightemperature paramagnetic behavior, and at low temperature, evidence for weak ferromagnetism, reinforced by a hysteresis loop at 2 K is F. Issaoui issawi fatma@yahoo.fr observed. The magnetic behavior of (C 7 H 18 N 2 ) CuCl 4 is attributed to Cu (II) due to the presence of an active JahnTeller effect in the d 9 electronic system, which give rise to short-range weak ferromagnetism.
