Source of materialAsolution of Cu(NO 3 ) 2 ×3H 2 O(24.2 mg,0.10mmol) in 1mlmeth-anol was slowly added to asolution of N,N-bis(o-hydroxyacetophenone)-l,2-diaminoethane (H 2 L)(14.8 mg, 0.05 mmol) in 3ml methanol with general stirring. The resulting mixture was placed in the dark, and black well shaped crystals were obtained after one day, in ayield of 46% (based on Cu). Experimental detailsHatoms were included in therefinement at calculated positions [C-H aromatic =0.93 Åwith U iso (H) =1.2U eq (C); C-H methyl =0.96 Å with U iso =1.5 U eq (C). DiscussionSchiff bases complexes are an important and popular area of research due to their simple synthesis, versatility, and diverse range of applications [1]. In particularly, alarge number of copper(II)-Schiff basescomplexes have been synthesized and characterized duet ot heir interestingp ropertiesa nd novelt opologies [ 2,3]. Herein, thetitle compound has been synthesized and its crystal structure has also been determined. The molecular structure of the title structure is made up of discrete neutral [Cu 2 (L)(NO 3 ) 2 ]. The metal center Cu(1) is sixfold coordinated by two phenoxo oxygen atomsand four oxygen atomsfrom two NO 3 -.The second metal center Cu(2) is coordinated to two phenoxo oxygen atomsa nd two imine nitrogen atomsf rom one ligand to exhibit as quare plane geometry. In the title complex, the bond lengths of Cu-O are in the range of 1.892(1) Åto2.426(2) Å, and the Cu-N bond distance is 1.910(2) Å, which are normally observed in Cu(II) complexes [4].

“…In particularly, alarge number of copper-azido compounds with interesting topologies have been well documented thanks to many possible bridging modes of the azido ligand and flexible coordination numbers of the Cu(II) ion [2][3][4][5][6][7].The molecular structure of the title compound consists of centrosymmetric tetranuclear molecule of formula [Cu 4 (mesalen) 2 (m 1,1 -N 3 ) 2 (N 3 ) 2 ](mesalen =(bis(ethane-1,2-diylbis((1-(2-oxidophenyl)ethyl)amido)), whicha re similara sthe previous tetranuclear copper compounds [8]. Each terminal copper Cu(1) ion is coordinated to two phenoxo oxygen atom and two imine nitrogen atomsf rom one ligand to exhibit as quare plane geometry.…”

A novel two dimensional (2D) copper(II) polymer [Cu 3 (N 3 ) 6 (DMF) 2 ] n (1) has been synthesized and characterized by elemental analysis, IR, X-ray single crystal diffraction and magnetic susceptibility measurements. Complex 1 was formed by a [Cu 3 (N 3 ) 6 (DMF) 2 ] trimeric unit through two double symmetric end-on (EO) azide bridges which further constructed 2-D network through asymmetric EO and end-end azide bridges. The magnetic study shows that the compound 1 exhibits ferromagnetic interactions through symmetric EO azide bridges and antiferromagnetic interactions via asymmetric EO azide bridges.
