The crystal structure was determined by single-crystal X-ray diffraction. The complex crystallizes in space group P21/c,with cell parameters a=0.605 6(5)nm,b=1.448 1(5) nm,c=1.711 9(5)nm,β=93.257(5)°,and V=1.498 9(14) nm3,Dc=1.497 g·cm-3,Z=2,F (000)=708,R=0.027 7,wR=0.072 5. The crystal structure shows that the nickel atom is coordinated with four nitrogen atoms from the two en and two oxygen atoms from two dpas to form a mononuclear complex. Furthermore,the adjacent complex units are extended into a 2D supramolecular network through hydrogen bonds.展开更多
