A new bis(salamo)-type ligand has been designed and synthesized,and its hetero-trinuclear [Cu(II)2Ca(II)] complex has been successfully prepared.It is characterized by elemental analyses,IR spectra,UV-Vis absorption spectra and X-ray single crystal diffraction.Meanwhile,Hirshfeld surfaces and fluorescence properties were investigated.The hetero-trinuclear [Cu(II)2Ca(II)] complex was obtained by 2 equiv.Cu(NO3)2 · 3H2O and 1 equiv.Ca(0Ac)2-2H2O with 1 equiv.H4L.Obviously,there is the ligand,metal Cu(II)and Ca(II)ratio of 1:2:1 which formed the hetero-trinuclear [Cu(II)2Ca(II)] complex.X-ray diffraction result showed that Cu(II)and Ca(II)atoms in the crystal are geometric polyhedrons with different shapes.Both Cu(II)atoms are located respectively in N202 cavities of the completely deprotonated ligand(L)~(4-)unit.Cu(II)and Ca(II)atoms are bridged by nitrate groups,so that the two Cu(II)(Cul and Cu2)atoms have slightly distorted square pyramid geometries.In addition,Ca(II)atom is located in a O6 cavity of the ligand(L)~(4-)unit and possesses square antiprism with eight coordination.
