The crystal structure of the compound with empirical formula [Cu (2, 2'-BP)Cl NO3]2 (BP: 2,2'-bipyridine) (1) has been determined. Crystals are triclinic, space group P-1 with a = 7.5152(12) Å, b = 9.2531(14) Å, c = 10.2834(16) Å, alpha =112.181(2)º, beta = 102.155(2)º, gamma = 105.617(2)º. The copper atom displays a (4+1) square pyramidal coordination, with the four in-plane bonds provided by one chloride ion, two nitrogen atoms from the 2,2'-bipyridine molecule and one oxygen from the nitrate group. The apical position corresponds to a chloride ion Cl(1') from a centrosymmetric neighboring moiety. The two symmetry related Cl ions bridge two copper atoms, generating a dimeric unit (Cu(1)-Cl(1) = 2.2726(11) Å, Cu(1)-Cl (1') = 2.7093(13) Å). Magnetic susceptibility measurements showed a weak ferromagnetic interaction between dimers
