Abstract: Geometric data from (1-aza-4-azoniabicyclo[2.2.2]octane-N1)(1,4-diazabicyclo[2.2.2]octane-N1)trichloromanganese(II), [MnCl3(C6H13N2)(C6H12N2)] or [MnCl3(Hdabco)(dabco)] (dabco is 1,4-diazabicyclo[2.2.2]octane), and the cobalt(II) analogue, [CoCl3(C6H13N2)(C6H12N2)], have been combined with previously reported data for the Ni and Cu analogues to show that bond-length trends across the isotypal series are consistent with a high-spin trigonal-bipyramidal system. As each transition metal is positioned on a D3 site in the space group R32 (No. 155), two bond lengths fully define each trigonal-bipyramidal coordination geometry [Mn-Cl = 2.3903 (7) Å and Mn-N = 2.367 (2) Å, and Co-Cl = 2.3080 (8) Å and Co-N = 2.269 (3) Å].
Formula: [MnCl3(C6H13N2)(C6H12N2)] and [CoCl3(C6H13N2)(C6H12N2)]
