A two-dimensional hydrogen-bonded cadmium(II) compound [Cd(dapm)2- (CH3COO)2(H2O)2](dapm=diaminodiphenylmethane)has been synthesized and characterized by single-crystal X-ray diffraction analysis.It crystallizes in monoclinic,space group C2/c with a=27.572(3),b=5.5064(5),c=23.310(2)A,β=124.785(1)°,C15H19Cdo.5ON2O3,Mr=331.52,V=2906.6(5)A3,Z=4,Dc=1.515 g/cm3,F(000)=1368 and μ=0.801 mm-1.The final R=0.0403 and wR=0.1014 for 1795 observed reflections with I≥4σ(I).The centrosymmetric Cd(II) is six-coordinated in a distorted octahedral geometry,and the dapm in a trans mode acts as a monoden-tate ligand.The intermolecular hydrogen bonds among coordinated aqua molecules with coordi-nated acetate oxygen atoms and uncoordinated dapm nitrogen atoms form a two-dimensional supramolecular framework.
