Abstract

The heteronuclear coordination polymer [Cd(SCN)2Ni(en)(NCS)2(EtOH)]21 (en = ethylenediamine) was obtained by reaction of Cd(NO3)2·4H2O, KSCN, Ni(NO3)2·6H2O and en in a mole ration of 1:3:1:0.1 in ethanol solution. The complex is characterized by IR spectroscopy, electronic spectroscopy and single-crystal X-ray diffraction analysis. Crystal structure analyses show that the title complex belongs to the triclinic space group P1¯ with a = 8.922(3), b = 9.860(3), c = 10.333(5) Å, α = 113.116(6)°, β = 106.550(6)°, γ = 101.622(4)°, V = 749.0(5) Å3. Cd(II) and Ni(II) centers are linked by di-μ-1,3-thiocyanate bridges to form a 2D network containing three types of 16-membered [Cd2Ni2(μ-1,3-SCN)4] macrocycles. Each Cd(II) center links six Ni(II) centers by six μ-1,3-SCN− bridges and each Ni(II) center links three Cd(II) centers by three μ-1,3-SCN− bridges. The luminescent properties of 1 in the solid state were investigated.
