  We report structural and physical properties of a new quasi-one-dimensional
Cr-based compound, KCr$_{3}$As$_{3}$, which is prepared by potassium
deintercalation from the superconductive K$_{2}$Cr$_{3}$As$_{3}$.
KCr$_{3}$As$_{3}$ adopts the TlFe$_{3}$Te$_{3}$-type structure with space group
$P6_{3}$/$m$ (No. 176). The high-temperature magnetic susceptibility obeys the
Curie-Weiss law with an effective magnetic moment of 0.68
$\mu_{\mathrm{B}}$/Cr. Below 56 K the susceptibility deviates from the
high-temperature Curie-Weiss behavior, coinciding with the rapid increase in
resistivity, which suggests formation of spin clusters. The short-range spin
correlations are also supported by the specific-heat data. The title material
does not exhibit bulk superconductivity; instead, it shows a cluster spin-glass
state below $\sim$ 5 K.
