Abstract

Graphical abstract: Three new 3d-4f heteronuclear one and two dimensional coordination polymers (CPs), {[Cu(L1 2− )Nd(NO3 )(µ-NO3 )(H2 O)2 ].NO3 }n (1 ), [Cu(L2 2− )Nd(IN − )(NO3 )2 ]n (2 ) and [Cu(L2 2− )Gd(IN)(NO3 )2 ]n (3 ), have been synthesized and characterized structurally and magnetically. Highlights: Three new 3d-4f heteronuclear one and two dimensional coordination polymers, have been synthesized. Complex 1 represents the first example of a nitrate bridged Cu(II)-Nd(III) zigzag one dimensional chain. Complexes 2 and 3 are isomorphous two dimensional coordination polymers. The magnetic study reveals that antiferromagnetic interactions exist between the Cu(II) and Nd(III) ions in 1 and 2, however a ferromagnetic interaction exists between the Cu(II) and Gd(III) ions in 3 . Abstract: Three new 3d-4f heteronuclear one and two dimensional coordination polymers (CPs), {[Cu(L1 2− )Nd(NO3 )(µ-NO3 )(H2 O)2 ].NO3 }n (1 ), [Cu(L2 2− )Nd(IN − )(NO3 )2 ]n (2 ) and [Cu(L2 2− )Gd(IN)(NO3 )2 ]n (3 ), have been synthesized and characterized by using FT-IR, elemental analysis, Hirshfeld surface analysis and single crystal X-ray diffraction study. Complex 1 represents the first example of a nitrate bridged Cu(II)-Nd(III) zigzag one dimensional chain, to the best of our knowledge. The X-ray crystal structure analysis reveals that complexes 2 and 3 are isomorphous two dimensional coordination polymers whose heterometallic dinuclear units of Cu-Nd in 2 and Cu-Gd in 3 are connected by the isonicotinate anion as a spacer. A magnetic study reveals that antiferromagnetic interactions exist between the Cu(II) and Nd(III) ions in 1 and 2, however ferromagnetic interactions exist between the Cu(II) and Gd(III) ions in 3 .
