title: KBa(2)InAs(3) with coexisting monomers of [In(2)As(7)](13-) and their one-dimensional polymers.
abstract: The title compound was made by fusion of a stoichiometric mixture of the pure elements. The structure (orthorhombic, Cmc2(1), Z = 16, a = 10.129(2) A, b = 25.208(4) A, c = 13.884(3) A) is made of isolated units of [In(2)As(7)](13-) and a polymer chain of [In(2)As(5)](7-) made of the same units. According to magnetic measurement, KBa(2)InAs(3) is a closed-shell compound, a Zintl phase.
