N2 - We report that the ternary (formula presented) compounds adopt an isostructural (formula presented)-type hexagonal structure in a relatively small range of nominal carbon concentration, (formula presented) The lattice parameter a decreases almost linearly with increasing carbon content x, while the c parameter remains unchanged, indicating that carbon is exclusively substituted in the boron honeycomb layer without affecting the interlayer interactions. The superconducting transition temperature (formula presented) decreases quasilinearly as a function of the carbon concentration, with a slope steeper than that for the isoelectronic (formula presented).
