Abstract: A novel one-dimensional chain coordination polymer{HgBr22-Cu(C26H22O2N4)]}n was synthesized bythe reaction of the building block CuL2 (L-=3-pyridylmethylsalicylideneimino) with HgBr2.X-ray single-crystal analysis reveals that the crystal of thetitle compound is monoclinic,space group C2/c with a=2.814 49(13) nm,b=0.624 53(3) nm,c=1.564 47(6) nm,β=114.808(4)°.The [CuL2] building unit in which the planar geometric Cu2+ is constructed by two phenol oxygen and two nitrogen atoms from two different L- in a trans arrangement,performs as a bidentate linker to bridge neighboring two HgBr2 to build a one-dimensional chain.Hg2+ adopts a distorted tetrahedral geometry constructed bytwo Br- ions and two N atoms.Interchain π…π weak interactions are observed between the chelating rings around Cu2+ cations and phenyl rings,whichleads chains packing into 2-D supramolecular structure along the crystallographic b-axis.

Key words: metalloligand, building block, synthesis, crystal structure
