Deprotonation of 4,4′-biphenyldicarboxylic acid (H2BPDC) with triethylamine followed by the copolymerization with Y(III) in N,N-dimethylformamide (DMF) at room temperature yields a new three-dimensional (3-D) porous metal–organic coordination network, [Y2(BPDC)3(DMF)2(H2O)2]n · (DMF)n · (H2O)n (1). Compound 1 (C24.50H19N1.50O9Y) crystallizes in the triclinic P-1 space group (a = 8.220 (2), b = 13.998 (4), c = 14.212 (4) Å, α = 111.058 (5)°, β = 90.187 (5)°, γ = 94.318 (5)°, V = 1520.9 (7) Å3, and Z = 2). X-ray crystallography reveals that 1 consists of a 3-D framework contained open 1-D channels with the dimension of 5 × 10 Å along the crystallographic a axis. The adsorption measurements show that compound 1 can adsorb N2, Ar and CO2 into its pores. The adsorption isotherms for MeOH and H2O were also measured.
