%X The crystal structure of the title compound, [Co(terpy)(CO3)(OH)],4H2O, has been determined at 295 K by single-crystal X-ray diffraction and the use of diffractometer data, and refined by least squares to a residual of 0.075 for 1354 ?observed? reflections. Crystals are triclinic, P&#299;, a 11.407(6), b 10.566(6), c 8.445(4) &#506;, &#945; 100.21(5), &#946; 107.35(5), &#947; 102.18(5)&#176;, Z2. The structure of the molecule is unusual for a 1 : 1 transition metal/terpy complex in that the other ligating atoms are non-halide and the complex six-coordinate. The remaining three coordination positions about the metal are occupied by the bidentate carbonate (Co-O 1.918(9), 1.918(8) &#506;) and the hydroxide ion (Co-O 1.894(10) &#506;). The Co-N distances are appreciably shorter than those observed in other terpy systems (Co-N(central) 1.848(8); Co-N(outer) 1.946(9), 1.952(9) &#506;).
