Five new metal-organic coordination polymers {[Cu₃(渭₂-OH)₂(atrz)₂(nph)₂(H₂O)₂]路2H₂O}_n (rong class="boldFont">1rong>), {[Cu₂(渭₃-OH)(atrz)(1,2,4-btc)]路2H₂O}_n (rong class="boldFont">2rong>), {[Cu₂(渭₃-OH)(atrz)(1,2,4-btc)(H₂O)]路H₂O}_n (rong class="boldFont">3rong>), [Cu(dth)_0.5(nph)(H₂O)]_n (rong class="boldFont">4rong>) and [Cu(dth)(Hnip)₂]_n (rong class="boldFont">5rong>) [atrz=4-amino-1,2,4-triazole, dth=N,N'-di(4H-1,2,4-triazole)hexanamide, H₂nph=3-nitrophthalic acid, 1,2,4-H₃btc=1,2,4-benzenetricarboxylic acid and H₂nip=5-nitroisophthalic acid] were hydrothermally synthesized and structurally characterized. Polymer rong class="boldFont">1rong> shows a one-dimensional (1D) chain. Polymers rong class="boldFont">2rong> and rong class="boldFont">3rong> exhibit similar tetranuclear Cu^II₄ cluster-based three-dimensional (3D) frameworks with the same components. Polymer rong class="boldFont">4rong> possesses a 3D framework with a 4¹²路6³-rong class="boldFont">pcurong> topology. Polymer rong class="boldFont">5rong> displays a 3D framework with a 4⁴路6¹⁰路8-rong class="boldFont">mabrong> topology. The magnetic properties of rong class="boldFont">1rong>-rong class="boldFont">4rong> were investigated.
