A novel heterometallic complex,[Zn4Ni(OH)2(btec)2(titb)2(H2O) 2]·2H2O (1) (H4btec=1,2,4,5-benzenetetracarboxylic acid,titb=1,3,5-tris(imidazol-l-ylmethyl)-2,4,6-trime-thylbenzene),has been hydrothermally prepared and characterized by IR spectroscopy,elemental analysis and single-crystal X-ray diffraction.The crystal is of triclinic system,space group P(1) with a=10.817(10),b=11.878(11),c=14.569(14) (A),α=71.762(12),β=76.122(13),γ=71.493(13)°,V=1665(3) (A)3,C62H62N12O22Zn4Ni,Mr=1647.43,Dc=1.643 g/cm3,F(000)=842,μ=1.784 mm-1 and Z=1.The final R=0.0531 and wR=0.0890 for 3545 observed reflections (I> 2σ(I)).In the title complex,the btec ligand acts as a five-dentate bridging ligand to link up zinc and nickel atoms into a lamellar framework,which are further interlinked into a 3-D framework via the titb ligands.
