Infrared dark clouds (IRDCs) are ubiquitous in the Milky Way, yet they play a crucial role in breeding newly-formed stars.\n  Aims. With the aim of further understanding the dynamics, chemistry, and evolution of IRDCs, we carried out multi-wavelength observations on a small sample.\n  Methods. We performed new observations with the IRAM 30 m and CSO 10.4 m telescopes, with tracers ${\\rm HCO^+}$, HCN, ${\\rm N_2H^+}$, ${\\rm C^{18}O}$, DCO$^+$, SiO, and DCN toward six IRDCs G031.97+00.07, G033.69-00.01, G034.43+00.24, G035.39-00.33, G038.95-00.47, and G053.11+00.05.\n  Results.
