Bis(2-amino-4-methyl-pyridinium) bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II).


ABSTRACT: The asymmetric unit of the title compound, (C(6)H(9)N(2))(2)[Cu(C(7)H(3)NO(4))(2)], contains half of a [Cu(pydc)(2)](2-) (pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid) anion and one protonated 2-amino-4-methyl-pyridine (2a4mpH)(+) counter-ion. The anion is a six-coordinated complex with a distorted CuN(2)O(4) octa-hedral geometry around the Cu(II) ion. N-H?O and C-H?O hydrogen bonds along with ?-? contacts between the pyridine rings of the (2a4mpH)(+) cations [centroid-centroid distance = 3.573?(2)?Å] stabilize the crystal structure.
