Single\u2010crystal X\u2010ray structures of <jats:bold>2<\/jats:bold>, <jats:bold>5<\/jats:bold> and <jats:bold>6<\/jats:bold> were determined.

The variable\u2010temperature (2\u2013300 K) magnetic susceptibilities of compounds <jats:bold>2<\/jats:bold>\u2013<jats:bold>6<\/jats:bold> have been measured.
