%X The crystal structure of the title compound, [CO(C15H11N3)2](ClO4)2.c. 1.3H2O has been determined by single crystal X-ray diffraction methods at 295 K. The structure is described in terms of atetragonal P42/n sub-lattice structure similar to that of [Co(terpy)2]I2.2H2O, with a 8.86(1), c 20.19(2) Å. Perchlorate orientation and disorder, however, demand consideration of superlattice structures in I 41/a//F41/d with 4 and 8 times the P41/n cell volume. The relationship between the general structural features of the [Co(terpy)2] X2 salts is described and discussed. The cobalt-nitrogen(central, distal) distances (2.03, 2.14 Å) are the longest observed in the [Co(terpy)2]2+ system, and are consistent with the unusually high magnetic moment of the salt (4.2 BM).
