The reaction of L-histidine, CdCl(2)(.)2.5H(2)O and 4,4'-bipyridine in methane/water gave rise to a two-dimensional coordination polymer [CdCl2(4,4'-bipyridine)](infinity) which has been characterized by single-crystal X-ray diffraction. The polymer crystallizes in the orthorhombic system, space group Cmmm with a = 12.083 (7), b = 11.771(7), c = 3.781(2) Angstrom, V = 537.8(6) Angstrom(3), Z = 2, C10H8N2CdCl2, M-r = 339.48, D-c = 2.097 g/cm(3), F(000) = 328 and mu(MoKalpha) = 2.490 mm(-1). The final R = 0.0658 and wR = 0.1398 for 257 observed reflections with I greater than or equal to 2sigma(I).
