The square antiprismtwisted square antiprism ratio in LnDOTAtetraamide chelates is a critical parameter in governing waterexchange kinetics and ultimately the utility of a chelate as a PARACEST MRI contrast agent.Twisted Antiprism. A twisted antiprism is obtained from an antiprism by rotating its top face by or; it has a nontrivial infinitesimal isometric deformation. The case of the twisted triangular antiprism is known as Wunderlich's (or Schoenhardt's) octahedron. According to the BlaschkeLiebmann theorem, four nonadjacent faces twisted square antiprism

Twisted prism. A twisted prism is a nonconvex prism polyhedron constructed by a uniform qprism with the side faces bisected on the square diagonal, and twisting the top, usually by q radians (180q degrees) in the same direction, causing side triangles to be concave.

In geometry, the square antiprism is the second in an infinite set of antiprisms formed by an evennumbered sequence of triangle sides closed by two polygon caps. It is also known as an anticube. It is also known as an anticube.twisted square antiprism The geometrical definition of an antiprism is a polyhedron composed of two parallel copies of some particular polygon, connected by an alternating band of triangles. Here I present a twist square antiprism box. In the first photo the colorchanged box is folded insideout.

Antiprism. Antiprisms are similar to prisms except the bases are twisted relative to each other, and that the side faces are triangles, rather than quadrilaterials. In the case of a regular n sided base, one usually considers the case where its copy is twisted by an angle \frac\pin. twisted square antiprism In geometry, the square antiprism is the second in an infinite set of antiprisms formed by an evennumbered sequence of triangle sides closed by two polygon caps. Twisted prism. A twisted prism can be made (clockwise or counterclockwise) with the same vertex arrangement. The water exchange kinetics of the mono capped twisted square antiprism (TSAP) being much closer to optimal than those of the mono capped square antiprism (SAP) render the TSAP isomer more desirable for high relaxivity applications. Abstract. The water exchange kinetics of the mono capped twisted square antiprism (TSAP) being much closer to optimal than those of the mono capped square antiprism (SAP) render the TSAP isomer more desirable for high relaxivity applications. Two systems have been developed that allow for selection of the TSAP coordination geometry in A twisted prism can be made (clockwise or counterclockwise) with the same vertex arrangement. The truncated square antiprism one in an infinite series of truncated antiprisms, constructed as a truncated square antiprism. It has 18 faces, 2 octagons, 8 hexagons, and 8 squares.
