A series of divalent metal diphenate (dip, biphenyl-2,2'-dicarboxylate) coordination polymers incorporating the kinked 4,4'-dipyridylamine (dpa) ligand has been hydrothermally synthesized and structurally characterized via single-crystal X-ray diffraction. {[Zn(dip)(dpa)]center dot 3H(2)O)(n) (1) and {[Cu-3(diP)(3)(dPa)(3)(H-2-O)(3.5)]center dot 2H(2)O}(n), (2) both display 2-D (4,4) grid topologies. {[Cu(dip)(dpa)]center dot H2O}(n) (3), a polytype of 2, possesses a non-interpenetrated 3-D 6(5)8 cds topology. {[Ni(dip)(dPa)(H2O)(2)]center dot[H2O)(n), (4) has a 2-D grid topology similar to I and 2. In contrast, the cadmium congener {[Cd-6(diP)(6)(H2O)(4)(dpa)(4)]center dot 5H(2)O}(n) (5) features [Cd-6(diP)(6)(H2O)(4)] arc-like hexanuclear clusters that link together into 1-D cadmium dicarboxylate rods, which are further pillared by dpa ligands to form a complicated 3-D coordination polymer lattice with a very rare 5-connected 4(4)6(6) nov 3-D non-interpenetrated cluster node topology. Thermal properties for all phases are presented, along with luminescent properties for 1 and 5.
