In the title metal-organic framework complex, {[Cu(C(4)H(4)-N(2))(2)](C(8)H(5)O(7)S)center dot H(2)O}(n) or {[Cu(I)(pyz)(2)](H(2)SIP)center dot H(2)O}(n) (pyz is pyrazine and H(3)SIP is 5-sulfoisophthalic acid or 3,5-dicarboxybenzenesulfonic acid), the asymmetric unit is composed of one copper(I) center, one whole pyrazine ligand, two half pyrazine ligands lying about inversion centres, one H(2)SIP(-) anion and one lattice water molecule, wherein each Cu(I) atom is in a slightly distorted tetrahedral coordination environment completed by four pyrazine N atoms, with the Cu-N bond lengths in the range 2.017 (3)-2.061 (3) angstrom. The structure features a three-dimensional diamondoid network with one-dimensional channels occupied by H(2)SIP(-) anions and lattice water molecules. Interestingly, the guest-water hydrogen-bonded network is also a diamondoid network, which interpenetrates the metal-pyrazine network.
