Figure 4
Pressure dependence of (a) the Co—N bond lengths and (b) the amide C—N—C bond angles for α-Co(dca)2 (solid markers) and γ-Co(dca)2 (hollow markers). The different Co—N bond lengths are shown in red (axial, amide nitrogen) and black (equatorial, cyanide nitrogen) to highlight the elongation of the CoII octahedral in α-Co(dca)2. For γ-Co(dca)2 the average of the two unique Co—Neq bond lengths are shown. Vertical dashed lines indicate transition pressure. Error bars are within the size of the data points. |
