Abstract
Meridional forms of N3S quadridentate complexes of the type [(en)Co(NH2(CH2)2 N=C(R′)CH2S(CH2)2NH2)]3+ with R′ = CH3 and NH2) are readily prepared from [(en)2Co(S(R)CH2CH2 NH2)]3+ (with R = CH2COCH3 and CH2CN, respectively; en = ethane-1,2-diamine) in basic solution. The X-ray crystallographic analysis of the complex with R1= NH2 was determined as the monohydrate of its triflate salt and shown to have a β-type configuration of the quadridentate. Crystals are monoclinic, space group C2/c with a 23.337(1), b 11.973(1), c 20.015(1) � , β 95.12(1)�, and Z 8. 3183 data with 1 ≥ 3 σ (1) were refined to conventional R factors of 0.056 and 0.072.
