Bis[N,N-dimethyl-1-(10H-pyrido[3,2-b][1,4]benzothia-zin-10-yl)propan-2-aminium] tetrakis-(thio-cyanato-?N)cobaltate(II).


ABSTRACT: The asymmetric unit of the title salt, (C(16)H(20)N(3)S)(2)[Co(NCS)(4)], comprises one monovalent isothio-pendylium cation and one-half of a divalent thio-cyanatocobaltate(II) anion (2 symmetry). The central thia-zine ring of the cation is slightly twisted in a boat-like fashion, with r.m.s. deviations from the mean plane of 0.272?(1) and 0.2852?(8)?Å for the N and S atoms. The mol-ecular structure of the cation is stabilized by an intra-molecular N-H?N hydrogen bond. Within the complex anion, the Co(II) atom is tetra-hedrally surrounded by four N atoms of the thio-cyanate ligands. ?-? stacking, with a distance of 3.7615?(10)?Å between the centroids of benzene and pyridine rings, helps to consolidate the packing.
