Two complexes, [Ag2(μ4-hmt)(μ3-oga)]·3H2O(1) and [Ag2(μ4-hmt)(μ 3-mpa)]·3H2O(2)(hmt=hexamethylenetetramine, oga=diglycolate, mpa=m- phthalate), have been synthesized and structurally characterized. The structures of these complexes consist of three-dimensional cationic honeycomblike networks. The dicaboxylates in these hexagonal channels function in monodentate-bidentate coordination mode. Complex 1(C10H22Ag2N4O8) crystallizes in the monoclinic space group P21/c, with a=0.6366(3)nm, b=1.1736(7)nm, c=2.1998(12)nm, β=97.60(6)°,V=1. 629(2)nm^3, Z=4, R1=0.0491, wR2=0.1231. Complex 2(C14H22Ag2N4O7) crystallizes in the monoclinic space group P21/c, with a=1.2944(4)nm, b=1.1998(7) nm, c=2.3491(14) nm, β=95.49(4)°, V=3.631(3)nm^3, Z=8, R1=0.0664, ωR2=0.1526.
