The title compound,[Cu2(DMPz)2PMo12O40]·HDMPz(1,DMPz=2,5-dimethyl pyrazine),has been synthesized and characterized by single-crystal X-ray diffraction analysis.It crystallizes in triclinic,space group P1 with a=11.075(2),b=11.551(2),c=11.886(2),α= 106.352(2),β=109.862(3),γ=109.504(1)°,V=1206.8(3) 3,C18H26Cu2Mo12N6O40P,Mr=2275.78,Z=1,Dc=3.131 g/cm3,μ=4.011 mm-1,F(000)=1073,S=1.066,the final R=0.0389 and wR=0.1056 for 3739 observed reflections with Ⅰ> 2σ(Ⅰ).The structural analysis indicates that the title compound is composed of Keggin clusters [PMo12O40]3-connected by one-dimensional [Cu(DMPz)]2n2n+ chains to form a two-dimensional grid layer with holes occupied by mono-protonated DMPz molecules.In the solid of the title compound,the 2D grid layers are stacked together in an ABAB packing mode.
