摘要: Abstract The crystal structure of B-chloro(RS-l,2-diaminopropane)(diethylenetriamine)cobalt(III) tetrachlorozincate(II) (one the seven isolated isomers) has been determined from three-dimensional X-ray data collected by counter methods at room temperature. crystals are monoclinic: space group C 4 s Cc, with four molecules in a unit cell dimensions = 9.744(2), b 13.263(3), c 13.955(2) A , β 95.26(1). Observed and calculated densities 1.79 1.77 g cm −3 . final value conventional R-factor (on F) 0.037 was obtained 1331 reflections having F 2 ⩾ 3σ( ). consists complex cation discrete anions. contains cobalt atom surrounded one chlorine five nitrogen atoms an approximately octahedral configuration.
