Two novel coordination compounds, [Zn(CBPP)2(H2O)2]·3H2O(1) and[Ag(CBPP)·2H2O](2)(HCBPP = 1-(4?-carboxylatobenzyl)-3-(pyrazin-2-yl)pyrazole), were hydrothermally synthesized and characterized. Compound 1 crystallizes in monoclinic, space group C2 with a = 26.221(4), b = 8.4211(7), c = 14.295(3) ?, β = 114.561(8)o, V = 2705.9(2) ?3, Dc = 1.587 g/cm3, C28H28Cl2N8O9 Zn, Mr = 685.97 F(000) = 1416, μ(Mo Kα) = 0.926 mm-1, Z = 4, R = 0.0287, w R = 0.1076 for 2818 observed reflections(I > 2σ(I)), and R = 0.0300, w R = 0.1110 for all data. In 1, each deprotonated CBPP-ligand with a bidentate coordination mode connects two Zn(II) atoms to generate a 1D helical chain along the b axis. The adjacent chains intersect with each other through hinged Zn(II) ions to build up an interesting two-dimensional network. Compound 2 crystallizes in monoclinic, space group P21/n with a = 6.3544(1), b = 11.7195(3), c = 19.3188(4) ?, β = 94.297(2)o, V = 1434.64(5) ?3, Dc = 1.894 g/cm3, C14H13 Ag N4O4, Mr = 409.15 F(000) = 816, μ(Mo Kα) = 11.536 mm-1, Z = 4, R = 0.0456 and w R = 0.1184 for 2402 observed reflections(I > 2σ(I)), and R = 0.0517, w R = 0.1275 for all data. In 2, each ligand binds two Ag(I) atoms in a tridentate coordination mode to form an infinite zigzag chain. Their thermal and photoluminescent properties were also investigated.
