Abstract
The crystal structure of the title compound has been determined by the heavy-atom method from X-ray diffracto-meter data and refined by block-diagonal least-squares to R 0·056 for 1891 observed reflections. Crystals are monoclinic, space group P21/n, a= 19·005(4), b= 15·598(3), c= 6·913(1)Å, β= 92·34(1)°, Z= 4. The quaterpyridyl ligand is planar and coplanar with the cobalt, the inner nitrogen atoms bonding to it at a shorter distance (1·855 ± 0·005) than the outer (1·97 ± 0·01 Å). Co–OH2 is 2·067(5) and Co–S 2·244(2)Å. The nitrate ion is disordered.Keywords
