“…Although a sizeable number of azido-bridged nickel(II) complexes have so far been reported [13][14][15], such complexes with reduced Schiff base ligands are rare. Herein, we describe the synthesis and characterization of two neutral end-on diazido-bridged nickel(II) complexes incorporating conformationally labile N,N,N-coordinating reduced Schiff bases.…”

Complexes of the general formula [Ni 2 L 2 (l 1,1 -N 3 ) 2 (N 3 ) 2 ] have been synthesised in good yields by reacting Ni(NO 3 ) 2 AE 6H 2 O with L in the presence of excess of sodium azide in methanol at room temperature. Here L is N,N-bis(2-pyridylmethyl)amine (L 1 ) and). The X-ray structures of both compounds reveal that the N,N,N coordinating reduced Schiff bases are ligated facially. The Ni-N azido -Ni angle is $100°and the NiÁ Á ÁNi separation is $3.2 Å . The variable temperature magnetic susceptibility measurements of the two complexes show ferromagnetic behavior.

“…In general, in the binuclear Ni(II) complexes with the core formula [Ni 2 (μ 1,1 -N 3 ) 2 ] 2+ the mono-, bi-, tri-or tetradentate ligands complete the coordination spheres of Ni(II) ions. 1,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]22 In some cases, the azide anions function as bridging and terminal ligands. 1,[7][8][9][10][11][12][13][14][15][16][17][18][19][20]22 Scheme 1.…”

Binuclear double end-on azido bridged Ni(II) complex (1) with composition [Ni2L2(?-1,1-N3)2(N3)2]?6H2O, (L = (E)-N,N,N-trimethyl-2-oxo-2-(2- -(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-amin) was synthesized and characterized by single-crystal X-ray diffraction method. Ni(II) ions are hexacoor-dinated with the tridentate heteroaromatic hydrazone-based ligand and three azido ligands (one terminal and two are end-on bridges). DFT calculations revealed that coupling between two Ni(II) centers is ferromagnetic in agreement with binuclear Ni(II) complexes with similar structures.

“…If these ions are not present, Fe 2 L 3 type complexes are formed, where two Fe complex units attached to each other with an oxide bridge [15,16]. In addition N À 3 ion has been known to be a suitable ligand for m-bridge since 1986 and there are numerous studies related to it [19][20][21][22][23][24][25][26].…”

Dinuclear Fe(III) complex / X-ray diffraction / Single crystal structure analysis / Magnetic properties / Thermal analysis Abstract. Fe(III) complexes were prepared by the reaction of two different ONNO type Schiff bases N,N 0 -bis (salicylidene)-1,3-propanediamine (LH 2 ) and N,N 0 -bis (salicylidene)-2,2 0 -dimethyl-1,3-propane diamine (LDMH 2 ) in N À 3 containing medium. The X-ray diffraction studies revealed that the complexes are of dinuclear type connected with m-1,1-azido bridges. It was observed from the
