Magnetization measurements at 0.1 K up to 52 T have been performed on a powder sample of [Ni(C9H24N4)(μ-N 3)](ClO4) which is regarded as an S = 1 antiferromagnetic bond alternating chain compound with no spin gap. No anomaly indicating an existence of a spin gap was observed at 0.1 K. The experimental result indicates that this compound is a gapless system with experimental accuracy.
