Popis:	The dinuclear nickel(II) complexes [Ni2(L-Et)(μ-1,3-N3)(N3)(H2O)]·[Ni2(L-Et)(μ-1,3-N3)(N3)(CH3OH)](NO3)2·H2O, (1) and [Ni2(L-Et)(μ-1,3-N3)(N3)(H2O)]NO3·H2O, (1′) (HL-Et = N,N,N′,N′-tetrakis[(1-ethyl-2-benzimidazolyl)methyl]-2-hydroxy-1,3-diaminopropane) bridged by one alkoxo of L-Et− and one azido were prepared and the crystal structure of 1 was determined by X-ray crystallography. Magnetic susceptibility measurements for 1′ from liquid helium temperature to room temperature showed an antiferromagnetically strong interaction (2J = −187 cm−1, H = −2JS1·S2).
