The synthesis of ionic complexes cadmium(II) chloride and cobalt(II) with N,N'-diethylthiourea (detu) ligands has not been previously reported. Therefore, in this research, the was carried out to study structure characterization two complex compounds. cadmium(II)-detu synthesized using direct reaction method a ratio between Cd(II) salt detu ligand 1:2. Meanwhile, cobalt(II)-detu Co(II) 2:4. hav...

Co5V2(P2O7)4 was crystallized by chemical vapour transport using HCl as transport agent. Its crystal structure is isotypic to that of Fe(II) 5Fe(III) 2(P2O7)4 and can be regarded as a member of the thortveitite structure family with corrugated layers of metal-oxygen polyhedra extending parallel to (010). Significant occupational disorder between cobalt(II) and vanadium(III) is observed. Four of...

Reducing hexaazatrinaphthylene (HAN) with potassium in the presence of 18-c-6 produces [{K(18-c-6)}HAN], which contains the S=1/2 radical [HAN](.-) . The [HAN](.-) radical can be transferred to the cobalt(II) amide [Co{N(SiMe3 )2 }2 ], forming [K(18-c-6)][(HAN){Co(N'')2 }3 ]; magnetic measurements on this compound reveal an S=4 spin system with strong cobalt-ligand antiferromagnetic exchange an...

The trinuclear title compound, [Co(3)(CH(3)COO)(4)(C(20)H(22)N(2)O(6))(2)]·2CH(2)Cl(2), contains mixed-valence cobalt ions in the following order Co(III)-Co(II)-Co(III) where all the three cobalt ions are hexa-coordinated. The central cobalt ion is situated on an inversion centre and is in an all-oxygen environment, coordinated by four phenolate O atoms and two O atoms from bridging acetate gro...
