title: First Cu(II) diamondoid net with 2-fold interpenetrating frameworks. The role of anions in the construction of the supramolecular arrays.
abstract: The synthesis and crystal structure of the three-dimensional coordination polymer of an angular dipyridyl ligand 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (L) and Cu(ClO(4))(2), exhibiting the first Cu(II) diamondoid network with 2-fold interpenetration, ([Cu(L)(2)(H(2)O)(2)](ClO(4))(OH)(H(2)O)(2.5))(n) (1), together with the Cu(OAc)(2) complex of L, [Cu(L)(2)(OAc)(2)(H(2)O)](H(2)O)(2)(CH(3)OH) (2), with an unexpected mononuclear structure, are reported. Crystal data for 1: tetragonal, space group I4(1)/a, a = b = 13.477(3) A, c = 46.167(13) A, Z = 8. Crystal data for 2: triclinic, space group P(-)1, a = 7.847(2) A, b = 13.189(4) A, c = 15.948(5) A, alpha = 75.225(7) degrees, beta = 79.945(6) degrees, gamma = 77.540(5) degrees, Z = 2. The magnetic properties and anion effect are also discussed.
