报道了一系列Zintl相化合物的Sn-119穆斯堡尔参数。含有M(5)SnX(3)组成的四面体配位锡的化合物（M = Na， K; X = P, As, Sb）具有与灰锡相近的化学同分异构体位移，可以认为是共价键的物质。组合物KSnX （X = As, Sb）和双层化合物MSn(2)X(2) （M = Na, Sr; X = As, Sb）的层状结构在畸变八面体环境中具有锡。化学同分异构体位移更接近于白锡，可以用金属键来解释。(C) 1995学术出版社，Inc。
The Sn-119 Mossbauer parameters for a range of Zintl phase compounds are reported. The compounds containing tetrahedrally coordinated tin of composition M(5)SnX(3) (M = Na, K; X = P, As, Sb) have chemical isomer shifts close to that of grey-tin and can be considered to be covalently bonded species. The layer structures of composition KSnX (X = As, Sb) and double-layer compounds MSn(2)X(2) (M = Na, Sr; X = As, Sb) have tin in a distorted octahedral environment. The chemical isomer shifts are closer to that of white-tin and can be interpreted in terms of metallic bonding. (C) 1995 Academic Press, Inc.
